thanks for the responses.
We have been looking at Clearaudio. Their Innovation has 3 Platter Variations: Basic 40mm plastic; Compact 70mm plastic; Innovation (Innovation Wood variation) 15mm stainless steel platter below the 70mm plastic: 85mm total.
Instinct says thicker/heavier/both plastic and metal better!!!

that's some serious weight, the bass has to be awesome.
My best bass came from my Thorens TD124, just under 8 lbs cast platter. The superfine fit of the shaft into the bearing was beyond amazing, it took quite a while for the air to get out allowing the platter to decend. When I watch manufacturers videos and see them put the platters in, they descend completely within seconds.
If you have ever left the room, come back, Thorens still not all the way down, you just smile. Were the Garrard 301 and 4001 bearing tolerances that refined?
