Looney Tunes 

This is an R rated route - I clicked the box but it didn't come up.

i don't think it really deserves an R. The guide book gives it one b/c before Old Reliable fell off, the opening sequence was 10' above a broken block landing. Now it's right off a nice flat gravel landing. The pro is less obvious than most LCC cracks, but you can get in a bomber piece every bodylength or so.

Not R....

yeah, not R

If you blow the crux you'll tap so if its not R then its at a minimum very intimidating for the .11 leader.

Got on this for the first time today, seconding, which was a good thing. I didn't fall, but wow, not my idea of a nice trad lead, for me at least. The bottom section seemed very heads up to me. Gear is possible and everything, but you better be on it, as you're placing from the crux stances, and you're close to the ground, but still high enough to get hurt.

The moves are all there on this climb. It's a little sketchy off the deck until you reach the quasi roof, but the pro is pretty good the whole way. Highly recommended.

This is definitely a classic! The crux is the bottom, however I found plenty of places to set cams down low if you want to protect it well. In other words it's only an R if you want it to be. Very clean route. Unforgetable moves with bomber holds just when you need them most. I didn't use anything bigger than a 0.4 Camalot.

Definitely not a classic! (at least not by itself) Maybe this shouldn't even be considered a route anymore... its a 40ft approach for the all the great climbing above the first set of chains.
Do yourself a favor and keep going higher, to the top of the wall.

Interesting to hear that the rockfall that destroyed Old Reliable actually made the landing of this climb better. Although I am still confused as the book says, to paraphrase, "hardly a chuckle. a groundfall is likely until an obvious nut placement 20 feet off the deck is attained and clipped." There is a bomber #3 and .4 camalot placement 8 feet of the ground, so does that mean that the initial climb was longer? I.e. rockfall raised the landing higher?
Definitely place another .4 camalot under the roof from the gaston stance before initiating the crux moves or you will hit the ground. Great climbing, and not R. Bring quite a few small tcu sized pieces up to .5 camalot.

"so does that mean that the initial climb was longer? I.e. rockfall raised the landing higher?"

Yes, the rockfall did raise the start up.
It used to be a lot more spooky than it is now.
Also I'm just guessing that Brad Gilbert, Lynn Wheeler and Jeff Alred, back in 1980 didn't have the swank BD racks of 2012.
None the less take this all the way to the top of Mother Of Pearl and
it's one of the best pitches in LCC.
