Mike,
I personally think the ratings are pretty close most of the time. Including the Valley as well. Not to say that there is the ocassional sandbag for sure Gotta love it when you whip on one of those
As far as the R Route on Fairview it is way cool must do. The crux my partner and I thought was on the 1st low angle greasy pitch. If you can do that pitch you can finish the route easily.
There are knobs but tune up on your crack skills to have a better time if you have not been.
Drop me a line Mike I got some recent photos laying around I can send you. Plus other useful camping info.
