Hi guys, right now I am using the Yonex RQiS 1 tour light. I have only had it since the beginning of November, but it seems like the top of the racquet is already wearing down a lot. I do have another bumper guard to put onto it, but if it goes as fast as the first one, I will have to replace it every month or so. Has anyone found the racquet to have durability problems? Or am I just unforgiving on my frame? Thanks in advance!
