One of the better control-oriented strings of the moment has passed the test: this is the Solinco Hyper-G 17 tested by myracket.nl player Mike. 
The striking, bright green Solinco Hyper-G has been scoring well in various tests for a long time. So it was high time to put this string in its favorite 1.20 mm thickness through the test myself. The Solinco Hyper-G 17 offers a good balance between power and control, above-average ball rotation, and is still quite comfortable for co-polyester standards. The string is easily comparable to the new string from Diadem, the Elite XT 17.

Stringing the string: The Solinco Hyper-G 17 is easy to string. Unlike, for example, the RS Lyon 1.20 or the YTEX Square-X 16L, the string is packed somewhat 'looser'. What I mean by this is that the string is not as tightly 'rolled up'. Because of this, you only need to let the string out slightly to be able to work with this string. Threading the cross strings goes quite easily. All in all, not much exciting about it.
Review:
I have already had the Solinco Hyper-G 17 pass the test before. Since I was also experimenting with rackets then, I found it difficult to pass a fair judgment on this string. So this time the string gets a second chance.
The Solinco Hyper-G 17 sits in terms of feel between the Tour Bite Soft and the Tour Bite, two other well-known strings from Solinco. I found the Tour Bite Soft too 'springy', I clearly missed a bit of control. The soft feel and damping of this string were very pleasant. The 'regular' Tour Bite is somewhat more robust and clearly more control-oriented, but also stiffer. The Solinco Hyper-G 17 goes towards the Tour Bite Soft in terms of comfort, but towards the Tour Bite in terms of control. I myself (and my shoulder) found this very pleasant because control and comfort can go perfectly together in this case. 
However, there is also plenty of life and power in the Solinco Hyper-G 17. But you will have to get most of the speed yourself from your swing. It is and remains a low-powered string. In that sense, the string does not offer as much dynamism as the Diadem Elite XT 17, one of my favorite strings. The Elite XT 17 also clearly offers more spin, due to the six-point (star-shaped) construction. Still, the Hyper-G does indeed offer above-average spin, which was nice to give my somewhat flatter groundstrokes a bit more margin. In terms of spin potential, the Tour Bite beats the Hyper-G. The Tour Bite grips the balls a bit more easily/has more ball pocketing. The tension maintenance of the Solinco Hyper-G is quite decent. The string is quite stable on this front. I also found the durability for a 1.20 string to be sufficient to good. Actually, the Solinco Hyper-G 17 scores a very solid pass in all areas. This makes it one of the better all-round polys.
