Doug, You may want to try some silk ribbon as an alternate drive belt. I have been experimenting with several samples of silk ribbon on my Galibier for the past few weeks, and I generally prefer it to the 1/2" mylar tape that you mention. Walker supplies 4mm silk ribbon with his Proscenium Gold table, which is where I got the idea. It's available at craft and embroidery stores. Of course, the ribbon needs to be cut and the ends joined with contact cement.
It's amazing how much the sound changes with different belt materials. The width of the silk ribbon has a major impact also, my favorite so far being the 4mm that I started out with.
