Don't get confused about Solar Slab....it is not just a route, but rather walls (lower and upper) consisting of many warm routes...there are three main walls facing south going back into the canyon, Solar Slab, Black Arch and Eagle.....only route I refuse to do roped in all of RR is Solar Slab the route.....way too touristy....but so you understand, there are a ton of good routes on the upper slab in your range, Arch Enemy, Sunflower and Sundog....all excellent 5.9's as well as on the lower slab, Belluahs Book, Sandstone Overcast, Sideline, Frieda's Flake....all good 5.9's. All on summitpost, all in Jerry's book. You climb a lower route to reach an upper route, makes for a 8-9 pitch day typically. Even triple combinations, one of my favorite at that grade, Beullahs Book to Arch Enemy (wicked experience) to tying into Sunflower.
Folks can become drones and play follow the leader around RR....might be 4 parties on Solar Slab, a 5th class scramble really, and not a soul on any of these other routes I mentioned. You want double ropes which everyone needs to progress to anyway if you are going to get serious with backcountry trad climbing so you can rap Solar Slab or Sundog on top and Johnny Vegas on the bottom, avoiding the gully which you will never find me in. Again....too many folks screwing around in there, might as well be at the mall.(or as Fossana said, you can walk over to the single rap into the painted bowl, it will extend your day considerably)
Helitrope (upper) and Horndogger (lower) not good routes. The last pitch of the Friar is very exciting. Solar Flare is a fun 5.10c on the lower wall.
