New mat for Rega P6?

I had a Rega P8. I ended up just placing an old, thick LP on the platter, and using that as a mat.  I also just placed the LP directly on the platter.  Lots of other options, and I don't think there's a wrong choice, as I didn't hear much of a difference regardless of what was used, so you may as well use something cheap. 

Try a Herbies. They make them in all thicknesses. Money back if not satisfied. It will change the sound, maybe for the better or maybe for the worse. Everyone gets into an uproar when I say this, but if the static is to a point where it’s making playing records unenjoyable, Gruv Glide will stop it dead. I had unending static issues when I had my Linn and GG cured it. Up to you.

Herbies or Achromat (3,5mm).

I had a Rega RP-6. Very nice tt. I have tried lots of mats, everything from soft felt mats to carbon fiber ones. I recently got hold of a tt mat called MyMat, which was made by one of A'gon's members. This is the most neutral (read best sounding) mat I ever owned. Unfortunately this member quit making it. I am fortunate to have one...
