I have 2 Tecnifibre 325 rackets and they have been strung and gripped exactly the same (heat shrink, replacement and over grip). Even right down to the same vibration dampeners and grip tape! One weighs 362g and the other weighs in at 348g.. My guess is that the weight differential is down to manufacturing as 2 rackets are nearly never the same. So ,I want to get the lighter one up to 362g but I am not very experienced in customising rackets, in terms of weight. I was just hoping that some people could help me with it and tell me where to add lead tape without altering sw and balance. Thanks in advance!
