I need a stringer bad. I don't have that much to spend on a stringer and have never strung a racquet in my life. I read the reviews for X-2 and most of which is positive. I read something about frame torsion with 2 point mount, will it be a problem for the X-2? I have 3 Wilson HPS 6.1 that needs restringing, and I'll probably only string these racquets.
