Have run RS29 Yellow front / RS14 Black rear and PFC97 front and rear. Could do a coin toss to decide which I liked better. But when you factor in cost and bedding, the PFC 97 comes out way on top. Ran the 97s again today at Lime Rock - fantastic pad!

I found that the PF97 performed great but transfered a lot of heat to the caliper and I boiled my Motul RBF600 fluid and turned my red calipers to a dark maroon purple and the white Porsche lettering on the caliper turned dark brown! YIKES! This was on my 07 997S.
I went back to the RS29 Pagid Yellow pad and do not have this issue as long as I do not use the pad past 50%.

Mike, probably does have to do with the track and amount of braking required. Lime Rock is a short but quick track (relatively high average speed). The straights are pretty short and the turn at the ends fast, so not a brake intensive track. Monticello, on the other hand, is frustratingly hard on the brakes. 150 MPH straight into a 40 MPH series of switch backs. Watkins Glen is a wonderful flowing track, long and quick, so to me not overly hard on brakes.
For all the pads I've tried, I would be very happy with Pagid 29s in my C2S if they weren't so much more expensive than the PFC 97s and I haven't experienced the negative heat issues you and others have reported.
One more thing I've posted before. When I asked the guys at Farnbacher Loles which pads they like for the 997S, the answer was "PFC 97".

For the Pagid users...Do you all grind down the leading edge on the pad to a 45 degree?
I have a bench grinder to try am accomplish this but what a pain and dirty unhealthy job.
Any other ideas on a better way to accomplish this?

OK so i used both PF97s and RS14s (blacks) last weekend during the NJMP club race. I used PF97s in 2 sprints and RS14s in 1 sprint and the enduro.
I think that the RS14 has more of an initial bite and better release (more on/off and less progressive than the PF97). The RS14 doesn't feel as smooth as the PF97, definitely goes through phases and makes all kinds of different sounds under duress however. Sometimes you feel that you are metal on metal. But overall, I prefer the RS14. Thanks for all your comments and answers.
