Technics SL-1210G Headshells, Record Weights, and Mats

I've been using a Stein platter mat since I got my 1200G and I'm quite happy with it, as I am with my Clearaudio Charisma II MM cart....

If you think the  Origin Live Gravity 1 is good, try the new Gravity 2...the differences are not subtle! Everything the G1 does the G2 does at least twice as good!

I did recently purchase a Basis Reflex Clamp (second hand), but I can't hear a difference.

I bought me GAE new in 2016 and have done a lot of experimenting and am still learning.  Some of the lessons have been hard.  Recently I bought AnalogMagik software for turntable setup and learned that the head shell that I have been using is heavy enough to cause the resonance frequency of the arm/cartridge combination to be too high.  My advice to you all is to stick with the OEM head shell.  I have tried every mat mentioned in this discussion plus ones made of leather, acrylic, the VPI one that came with my HW-40 (why not?), and old record, and a few more.  By far the best for me so far is the Origin Stratos.  I have spent big bucks on record weights, but keep coming back to the KAB record clamp as the best overall.  I honestly prefer clamps to weights.

Is there anywhere in the US I can buy a Origin Live Strata Mat?  Duty and shipping from the UK make it pretty expensive!
