hi guys i was using the stock K90 (America version) and i read that this racket is 12 points head light on its spec. I have another one that is Asian version and it's 9 points head light, as my games improved i actually found that i played better with the asian version! (I can feel it clearly, and I don't know why. maybe it's like 20 grams less than the usa version? or maybe because the balance?) so my question is, how to turn my america K90 to 9 points head light? I think weight is not really a problem for me i mean it's just 20 grams and also i feel almost no weight diff by these 2 sticks. and as far as i know i can buy some lead tapes i guess? but i have no idea how to do that with my racket to turn it into 9 points head light Thanks for reading and helping!really appreciate it!!
