Hi everyone. I have been using the wilson hyper hammer 5.3 mp for a number of years and felt that it got better as is got older. I just managed to pick up a near new one that seems alot stiffer than my old faithful. Is there anyway to get the new frame to be a little more flexible? I am guessing that frames lose stiffness over time. Do I just need to hit another trillion balls to decrease the stiffness? Hope not. Any suggestions?
