Good start to the list. I think Audio Technix is a vendor, maybe they will send you a tile of 60 and 80 mil. If you want I can email them and ask.

That GTMat Pro could be confusing for people buying it. Usually 2 different spec products are not called the same thing. ---> Just looked on their site and the 100 mil doesn't say Pro. http://www.gtmat.com/gt_mat_sound_de..._products.html
