Turntable mat options

On the subject of Rega TT's, is there a clamp preferred for the short spindle of the subplatter on these? Most I have found specifically say they don't work on Rega TT's. Regarding mats, I've tried a few and always go back to the felt.

You sweet talking Devil you......
You just have such a way with words.
Takes my breath away.

I was going to just leave you to your delusions but.... I'm not that guy.

But before I go any further I just want us to be clear that you are going on record ( sic) here on Audiogon as saying....

In your system to your ears you cannot tell any difference between;
No mat, felt mat, rubber mat, foam mat, vinyl mat, acrylic mat, brass mat, cork mat, aluminum mat, leather mat, glass mat and any other material anybody may have tried.
All adjusted for correct vta, sra and azimuth of course....

I really like my Origin Live mat. Its a composite of rubber and cork.

I replaced the rubber mat on my Technics SL1200G with the Oracle record mat.  It made a world of difference.  Much better definition. It goes for around $200.00.
