Hey all! It's been a while since I've seen a post about this, but has anyone changed the original handle of a racket to their preferred handle size? Trying to find 4UG5 88Ds in the UK is pretty difficult and 88D stock in Asia seems to be low, as there's the new 88D Pro. I've managed to get 4UG4s, but I was thinking of swapping the handle from G4 to a G5. Wondering if anyone has tried it recently? Any tips and tricks to do it?
