I just bought those same pads locally, yesterday, for $9 each; manufactured by a company called "Edge", right? The colorcoding for cutting ability is different, though; isn't a black CMA/Lake pad a finishing pad? A black Edge pad is a heavy cut pad. No matter, it says what it is on the rear of the pad.
Also; THIS PAD MAY BE DIFFERENT FROM THE ONES REFERRED TO IN THE OTHER THREAD. I just went down to the garage and measured it, the 6.5" backing plate of the PC is indeed 1" smaller than the back of the pad; notice, the TOL site says "requires the 7.5" velcro backing plate". In the referenced thread, posters mention a total pad diameter of 7.5", these are more like 9".
I personally don't think it will make any difference, and I intend to use them with the 6.5" plate, but I haven't actually done that yet. From what I understand, they are regarded in the paint / auto body industry as a high quality pad.
