I bought a pure storm off of a buddy of mine two weeks ago, and love most things about it. I added some lead to the hoop at 9 and 3 oclock and it makes a big difference. the one question i have know is strings. He had it strung with alu power rough which is my usual string, but the difference is I normally use around 55 or 56 pounds with big banger and he's got it strung at 64 pounds. Any recommendations on tension? The racquet seems more flexible than my APD, but I'm worried that going too low on the storm tension will have me spraying balls.
