Anyone used a non-Basis Clamp on their Basis TT?

I am researching a Basis TT and what clamp to purchase. Has anyone experimented with the Basis table with the Basis clamp vs. the TT with a non-Basis clamp?
Friend of mine with a Basis/Rega/Grado Platinum setup bought a Michell clamp and also tried out a felt mat and my Ringmat. We agreed that it sounded best with no clamp or mat at all. Surprised both of us. One thing we didn't try is the Basis clamp. Obviously, YMMV.
u might try the Harmonix record clamp. works well on my Yorke...designed to manage micro-vibrations, might even try an outside record weight :-)
