I just bought three packs of VS 15 Touch for 25$ each. Before I was using champions choice (on a discount from my coach from wilson), after playing 4 matches in one day I think the Alu Rough was getting to my arm. I'm going to try to string one of my raquets with full VS 15 Touch. What should I string it at? In the champions choice I strung the gut at 60 and Alu Rough at 58. Should I go even higher than 60? Insight is very appreciated, thanks.
