I love it, Swampwalker! I still have fond memories of that table.
I want to try a mat, but I also want to continue using my clamp. I've thought about a custom cut Herbie's Grungebuster (and maybe having a custom cut piece to fit underneath the clamp as well). As I mentioned above, I'd really like to collect another platter to evaluate the differences. Not really interested in dumping my solid acrylic platter, though. I've got a OL Silver mk3 (I believe) and a Sound Smith Aida (love this cart).
