Hey guys. I have an 11 year old brother who is a top 15 player in the state. His racquet is the Wilson BLX Six One Lite, and he uses Wilson Sensation at 58 lbs. He wants to use a string that has more pop, so he is thinking of using a hybrid with Luxilon and synthetic gut (Prince). What Luxilon string do you recommend for him, and do you guys think Luxilon would hurt his arm? Thanks in advance.
