the salesman doesn't really know what he's talking about, if your
praphrasing is reasonably accurate.  i have used both kinds, as well as
glass, ceramic, and fibrous mats.  i'll stay with my conductive rubber
Angstrom and clamp.  you can try a Nagaoka rubber record clamp, but i
am of the opinion that unless the platter mat is of the right rubber,
you will not be getting all your money's worth.  the mission mat,
sorbomat, platter matter, or any of those type of mats are best, and
should be used with a clamp.  the key is very high damping in the mat
with tight coupling to the mat by a clamp.  if nothing else, your warp
problems will be reduced, reducing warp induced flutter.
