Hello guys, I've got a few Head Radical Liquidmetals with 4 3/8 grip size. I've borrowed a similar model from a friend(same grip size), and did notice that the grip on his racquet feels thinner(using the same overgrip, Wilson Pro) probably due to time/heavy usage. How can I make both my racquets feel the same, by changing the grip of overgrip? Please advise. Thanks!
