Thanks for your reply. It doesn't answer my questions though. It seems to me the weight difference is much higher in the IG models than the non IG models.
I have a scale, balance board, lead tape etc., but i dont feel that i have to ask/pay TW to customise a racquet because the actual specs are too different from what it should be.
So, theoretically, i should ask/pay TW to find me two racquets that actually weigh as much as they're supposed to
I'm not ok with that.
