I believe the G-Loc GS1 pads are in the same category as those. I have them and am pleased. They are fantastic for heavy "spirited" street use. I can only assume they'd be OK for the occasional track day auto-x use.

The initial bite is good when cold and better when hot. No bedding procedure needed (according to G-Loc), just drive as you normally would and they'll break in just fine. But they do (did for me) take a few miles to break in. I also installed new Centric Premium rotors while I was at it. As to dusting, it's not too bad and requires cleaning every 2 weeks.

If ya didn't know, G-Loc was formed by two guys that left Carbotech to start their own company. And the GS1s are comparable to the Carbotech 1521 compound which I believe is comparable to the 3 you listed. Just another option for ya to look into. But from what I've found there doesn't seem to be that many people using the GS1s, or at least those that are talking about them.
