I have pagid greys. I got mine as they were going cheaper than normal yellows and blues at the time, but would probably go again. Real strong bite and absolutely zero fade. On the few occasions when I have really warmed them up (where standards would be dripping off like treacle) they became frighteningly strong. On a track i imagine the disks would wear away before these things faded. Maybe the colours in between would be better for fast road though tbh.
