^ Why would it possibly be ruined? Racquets break down with each restring. You're going from 0kg of force to ~25kg of force through a small piece of graphite. Do you realise how heavy 25kg is? The bonds between the graphite fibres break down each time.
All I'm wanting to do is speed up the process until it starts feeling level with the 2nd racquet. I don't see anything wrong with that. I'm curious as to how long that is likely to take and what might be the best method - hence the thread.
