I have a Yonex RDX 500 racket in 4 1/2 grip size. It's in 8/10 condition. The grip size is too big for me so I'd be willing to trade it for a similar racket in 4 1/4 or maybe even 4 3/8 grip size. I also have a new grommet set to go with it. If I don't find anyone that wants to trade for it, I'd like to get $85 shipped for it. I have plenty of references on this forum. My email is czech09(at)gmail(dot)com. Thanks.
