Teammate is looking to reduce handle size of a Wilson Triad 3.0 from 5/8 to 1/2. Underneath the grip I found what appears to be a plastic-like covering over the handle. Looks as though removing it could very easily result in 1/8 reduction in size. It is seemless and runs the length of the handle. It will likely take a tin snips to cut through it. It seems like it may have been added to build up the size. I do not recognize it as a shrink sleeve, though it may very well be one. Has anyone ever seen anything like this before?? Could it have been added by Wilson?? As far as I know, the racquet was bought new, maybe from one of the big box stores.
