Steve, the RR is surprisingly friendly to drive, much better than the R1's I've had a lot of time on in enduros. A lot remains to be seen on longevity, but it's critical that we get the setup right before passing judgement on it.
I suspect you may be right on the camber issue. If you look at the Specs, we now run at the lower range, and the RR's are certainly spec'd to run a lot of camber - up to 5 degrees (!)
Next weekend, I can gather some tire temp data, and see if a little more camber pays off.
