If you have a 2 hander, I am not sure why you like the smaller heads so much. Well, I DO understand in a way, but honestly arm health is everything. I can tell you since going up to a 100 (even though I resisted this for a while), the results speak for themselves on my backhand. HUGE improvement especially hitting with 4.5s and 5.0s.
This stick is so good for your arm that you should revisit it again if you are dealing with an injury. Being sidelined sucks. I would put this racquet above the PKs in terms of arm safety, and that is saying a lot.
Hopefully that Platinum will help you out as well...but make sure and replace that poly with soft strings at bare minimum. Full poly is going to make everything worse.
