Grommet / bumper sets for out-of-production racquets? Any ideas on finding grommet / bumper sets for out of production racquets? I'd love to replace the sets on my Dunlop Revelation Select Pros, one of them has a bumper that's completely worn through to the frame. I looked at the Dunlop racquetsports web page, but it looks completely out of date. The contact information is for their US distributor, and I thought I read something here about them changing distributors. I've searched Google and online auctions with no luck.
