Developed with the help of Donald Young, once the highest ratest prospect in American tennis and an ATP touring pro, Hyper-G is an instantly recognisable bright green co-poly string from Solinco.
A square-shaped co-polyester, it's marketed as being able to produce an impressive combination of spin and precision.
Since launch, it's uptake on both the tour and at club level as being widespread, with big hitters like Sam Querrey choosing it as it allows him to take massive cuts at the ball without having to worry about overhitting.
So how does Solinco Hyper G play? Is it a good choice for a first foray into polyester strings? Or is it more suited to advanced level players who hit heavy? Let's take a look in this full Solinco Hyper G review.
Solinco Hyper G Specification
A newly developed, high performance and versatile co-polyester string designed to offer more playability and control while generating extreme power and intense spin and bite. Utilises a newly developed chemical formula in combination with the high powered polyester monofilament fibre designed and shaped to generate maximum power and control while amplifying the spin and bite intensity of the ball.

How it looks
A major question I had about this report was how many words I would write before “green” appeared. I resisted for 16 of them (original joke here), and it’s far from being my favourite colour, besides being a bit unfair because there are other similar looking strings out there.
The string surely looks snazzy on that black, grey and yellow frame, and all sorts of exotic or garish results are to be expected on other frames. Now that we’ve put this theme out of the way let’s get into the subject proper.
Hyper-G was launched around 2015 with a contribution by Donald Young and it seems to have become quite popular since, with a few professionals on tour using it.
It is a very slick string with a square cross-section, similar to Black Code 4S and several others. This geometric feature has a couple of benefits.
For me, the most important one is delaying the notching and allowing the strings to slide and snap back easily.
That deformation is a plague that affects most polyester strings, especially softer ones (that’s not quite the case of Hyper-G) because it makes the response very scratchy as the main strings struggle to leave the groove they carve on the crosses with repeated hitting; to make things worse, the more spin one places on the shot, the more noticeable it gets.
So, the resistance to notching a significant added value to a string because it removes one of the ageing signs in polyester strings, the other one being the loss of elasticity.
How Solinco Hyper G Plays
It took about half an hour of hitting until I formed an impression about the feel of Hyper G and how to compare it with other polyester strings. There didn’t seem to be any particular attribute that stood out.
Feel and Groundstrokes
The response is firm as would be expected from polyester, but not uncomfortable at all. The impact is on the muted side but still produces an audible pop. It’s more pleasant than the harsh crack given by Black Code and certainly distant from the metallic clang produced by Luxilon Alu Power or even from its softer sibling Adrenaline.
The feedback is not the most exuberant and the feel/touch is a little distant, although its still enough to get a reasonable feel about the stroke quality.
The tolerance to off-centre hits is excellent, above the average among the polyester strings I’ve tried so far. There is a gradual drop in power return, but without the accompanying vibrations found on Black Code andVolklCyclone, for instance, so you won’t get the feeling that on the next bad shot you will have your arm ripped off.
As a side note, it should be mentioned that the Pro Open frame used in the test is not as stiff as the Pure DriveI use more often, so this should also be taken into account. Moreover, I had to interrupt the first test session due to a loose butt cap, only to discover that the frame is filled with foam, upon fixing it back in place later that evening.
Control and Spin
As for control, forehands and backhands were easy to place accurately thanks to the string’s predictability, with the right amount of elasticity on slower strokes and a linear response when going for that little extra.
Hyper-G feels as if the ball sinks just a little more in the string bed when compared to stiffer strings, which is commonly described as “ball pocketing”.
This is mostly a matter of taste, as some players seem to prefer the sensation of control provided by an unshakable plank. If that's the case, I don’t anticipate that hyper-G would feel that harsh at25 kg, as long as the frame is hefty enough.
On slower strokes, especially on touch shots, it was a little strange that it didn’t feel as responsive as RPM Blast. This is somewhat surprising given that RPM Blast is an absolute beast of a string when going full throttle. I think that Hyper-G loses a few points here, although it compensates with a little more comfort on harder strokes.
The spin is adequate, although not the same “too-easy-sometimes-too-much” one gets with RPM Blast or Black Widow – this can be partly imputed to the frame because the central 4 main strings are closer together than on many other “tweener” frames – but it’s available in good amounts and easy to dose. It will just make you work a little harder to get the really heavy spin.
Confirming the initial observations, there was not the slightest glimpse of notching, as after 4 or 5 hours the strings keep sliding very smoothly. After a similar period, RPM Blast was already visibly and audibly notched, and Black Widow is even worse, so Hyper-G deserves a full 5 stars in this department.
One might expect from the previous assessments that Hyper-G lends itself well to flatter and/or a more relaxed game, and that’s indeed the case.
This is mainly for two reasons:
- The medium stiffness (as it is felt, not specifically the measured value) that provides a surprisingly easier than expected access to power and depth
- The good vibration dampening that makes for a comfortable response without feeling too mushy or vague; indeed, there’s even a little liveliness that is very welcome for those who prefer more responsive polyesters.
Note that polyester strings are not usually very friendly on flat strokes, so Hyper-G earns a very honourable mention here.
At this point, if you notice the emergence of a general pattern – “very adequate”, “correct”, “medium” – you are absolutely right, and it starts the explain the difficulties felt at the beginning about what to make of Hyper-G.
There is nothing very unusual to report about power, which is what one expects from polyesters, but if anything, I found a little more than with other strings in the same class.
For those with fully developed strokes, it might be just a bit too much, and the occasional long ball is likely to occur. Still, since Hyper-G is not too stiff, there is some room to increase the tension to cut down the elasticity without making it too uncomfortable.
Things started to shift slightly when stepping up at the service line.
Despite the relative elasticity of Hyper-G, it’s not a string for those with weak muscles or underdeveloped service motion.
Against an incoming ball, as in groundstrokes or volleys, one can use some of that energy to direct it back decently fast. But starting from zero speed as in services, it’s a different story altogether.
All the power must come from the player, and this is where I consistently find the biggest difficulties with polyester strings. In this regard, Hyper-G is not very different from the others, and it requires a full and decided swing to get the ball going with a purpose.
It’s a string that will not assist you a lot with power or depth, so it’s all on the player’s shoulders. When one puts more spin on the services, the inevitable trade-off is a loss in linear ball speed.
Fortunately, the amount of spin available is perfectly adequate (here we go again) to curb the trajectory just enough and not take away too much depth, so even if you tend to overcook the spin (slice or kick) with a very choppy movement, the loss in depth will not be very important.
This is where I enjoyed Hyper G the most. In an almost opposite manner to services, I find polyester strings great on volleys, if not for anything else, at the very least because if one misjudges the speed of the incoming ball, the deader response will lower the risk of volleys with a little more drive sailing long.
Hyper-G provides very direct feedback on volleys, and since it is quite tolerant to off-centre hits – which frequently happens on reflex shots –the success rate is high.
There is still enough elasticity for the put-away volley, but it works its best when going for more precision. I have absolutely no complaints here; Hyper-G is a very dependable string on the net.
How To Get the Most of Solinco Hyper G
Hyper-G is not the stiffest string I’ve tried, so it can be an interesting option for frames weighing around 280 g or more, unstrung. On even lighter frames it will not add any much and will make one work too hard to get some decent power and some uninvited discomfort with it.
On the other hand, Hyper-G may suit quite well a medium-weight, stiff, and powerful tweener to tone down the response without much negative impact on the comfort.
On heavier “player frames” it’s a no-brainer, and there seems to be plenty of room to play with the tension to adjust the response.
Hyper-G is one worthy option for more advanced players used to stiff polyester strings like Alu Power or RPM Blast and would like to try a more tolerant string without giving away much crispness.
Beginners, as usual, will not benefit much from it, but if one must really give it a go, I suggest stringing at low tension.

If I had to summarize Hyper-G's properties, it would be that it stands out by not standing out in a particular area.
For someone looking for things such as “insane spin”, “outstanding control”, “magnificent feel”, “I made an NRTP 6.0 player eat two bagels just because of these strings”, there is some disappointment to be had, as I can hardly fit a superlative next to any of Hyper-G's individual attributes.
However, when you consider the compromises that polyester strings usually represent in balancing crispness, comfort, feedback, elasticity, control, and so on – usually at the expense of at least one of them – this is something that Solinco is to be commended for.
Unless you are too picky about a certain aspect of a string, there is enough of just about every attribute to please a wide range of playing styles: decent power, predictable spin, and acceptable comfort, all of which making Hyper-G a versatile polyester. Now I've really exhausted my repertoire of mild adjectives 🙂
