I was hitting with some poly the other day and noticed some discomfort in my elbow. I just started after a very long break. I have a set of BDE gut lying around. Would this be the way to go while my arms get used to the pounding again? Would 66 lbs be too tight? Oh yah, it'll go in my RETIRED ProStaff 6.1 classic or a MegaAge racquet, while I demo some more racquets. Thanks. Any other tips appreciated.
