Okay, I just bought a used white Tom's Reach Machine. I question to all of you who know more than me is this: is it possible to replace the pallet from an L4 to an L3 size? I was told that Kneissl does not use a pallet system and that all of it's rackets are a one piece design. The grip size that I bought was a 4 1/2 and I want to get it down to a 4 3/8. So what are my options? Can I sand it down? Should I have a professional do that?
