I've been trying a handful of strings (Black Widow, Syn Gut, Moto16) and this stuff seems to fit my game pretty well. The power feels good, the control is great and the durability seems to be holding up. I'm on my second set and so far I haven't felt the need to try different strings. In addition, I don't have any arm pain like I've received with some of the other polys I've tried. My level is 4.0 and I strung my racquets at 54. Overall, solid product which I will keep as my go to string......for now.
