The R is the crux stem, but it's a very soft R. The bolt almost helped, but Tbone is right, it's worthless. Jimmy in some wires, fire the crux, then put in a good cam. The fall is fine. I wouldn't belay at the bolt either. A better stance is below the crux about 20 feet or so.
The first section is totally hands and big hands with cams galore. You belay, then it narrows to fingers and a seam. You can put in good gear below the crux, but not actually in the crux. Right above the crux you have good gear again. The climbing is easier with a jumbly crack, but kinda funky like Tbone said. The exit move that goes right is a bit unnerving, but safe. If the thing was downrated to PG, it would be fine with me. You can belay above the crux before you head right, or run it together and get a bit of rope drag.
If you're still not sure, you can always put a big TR on the whole thing pretty easily. Belay from the top.
I'm gonna go do it very soon I think. I felt really good on Long Live Trad this weekend even after taking the whipper. One or two more single pitch 5.10s to get the blood flowing real nice and I'll go out there and hike the sucker.
