I'm also using a Herbie's Mat with my Rega P9. The thickness does not have to be an issue since they are available in different thicknesses. You can call and talk with Steve and he'll send you the correct mat. It did not affect my VTA on the P9. Using it with a Lyra cartridge. Level, to a bit low on the rear of the arm seems to do it.
Also, I just noticed that the web site is recommending the "grungebuster" specifically for the P-9. That's new from a year ago when I bought.
Steve also offers a 90 day no-risk trial on his products and a lifetime warranty.
Good luck...
Paul
