This is a great string, with excellent access to spin and better touch than most other poly strings. The best combo I have found in years of trying is this string on the mains and the Gamma TNT2 on the crosses. I play 4.5 mens tennis and hit with a Wilson 6.1 95 16x18 (2012 model). This is a great setup overall.
I bought Gamma Moto 17, looking for a similar string to RPM Blast. Moto 17 Has excellent ball bit on all strokes and hold tension very well. It has a bit better touch and the price is just right!
