OK folks, leaving cones, pods and other footware alone for a moment, have you experimented with homegrown platforms other than granite? I am thinking of sandwich construction: e.g. start with three or 4 layers of 3/4 inch Baltic Birch plywood, and top the wafer with a sheet of Dupont Corion or reconstituted quartzite, such as 30 mm slabs of Dupont Zodiac or Stylestone.
