Currently using a cayman tnt-90. it's 85sq.in. headsize even though it's called the tnt90 and it has a sticker label on the throat saying it's 90" headsize. I started hitting with this random guy i met at the courts. I'm 5'4"ish and he's like 6'7"+ and pretty big guy. So of course his hits are pretty darn strong. But even though i'm a small guy I still manage to generate a lot of power using my entire body. But i've been noticing that even with the leaded 85, it's very stressful to hit all those big returns. whenever my racquet hits his ball it's like BANG BANG BANG!! very scary~ When I switch to my ncode 90, it's much easier to fight back his power. It's strange even though my 85" racquet is heavier than the ncode! (12.8oz vs. 12.3oz) I have lead tape at 3 and 9oclock rite now.. Should I add more lead tape at 12 oclock? Right now it's about 8pts head light.. adding to the 12 position will probably bring it closer to Even Balance. But i'm also worried that my arm can't handle the extra weight.
