I just wanted to say that the RDX 500 Mid is a great stick! Harryz sold me a brand new one so I strung it up and played a couple of sets with it tonight and, wow, what a pleasant surprise. I found it to be just as nice as the RDS 001 Mid, and possibly a little better. Anyone else play with the RDX 500 Mid for a long time and love it? I'm gonna have to play with it some more to see how much I really like it but so far I'm impressed. It's not replacing my Prestige Mid but it's one of the best 90" Yonex frames I've ever hit with.
