I just ran PFC08's for the first time coming from 01's and Hawk HT10/14's. The PFC08's have the spring clips which cures the low speed rattle. They don't have the bite of the 01's but they're more consistent when really hot and warming up. The 01's seemed to change a lot during temp changes. So far, happy camper with 08's and don't think I'll be back to 01's.
Oh...and right now I have 01's in the rear and 08's in the front. The bias is not a problem until the pads really get worked, then I can feel the rear's biting harder. Trail braking is really easy though.
