Nothing was different except the racket weight. I know I was trying to get the same penetration with my shots as I can with the 93, so maybe I have over strained a bit.
I have the week to rest it but I might go back to the 93, I dont want to injure myself and I just cant take a break lol, I did that when I ruptured my calf muscles and it was horrible.
Either that or get a nice arm friendly racket thats around the 300-310g mark.
improving technique is first though.
