I'm switching from Cool Carbon to Pagids.
Cool carbons performed great but would start to fade after a few laps. Of course it's 100F and a on very fast with some brake heavy turns. Cool carbons provide plenty of warning prior to losing complete effectiveness. A cool down between sessions 45min to 1 hour sessions was sufficient to get braking performance back. I hope the Pagids will provide a bit more time, otherwise I'll go back to the $200/set Cool Carbons.
