I finally led Disaster Factor. I placed a Camalot 4.5 below the first chockstone, then slung that, and pulled the Camalot, I placed a #4 Bigbro about halfway between chockstones. Finally, I chickened out and placed a big nut in the crack to the right before squeezing into the crack below the big second chockstone and hauling up onto it, what I thought was the hardest move. I didn't bother to sling it because once on top of if you have a nice little crack that takes all sorts of nuts. I placed the big camalot up under the leaning slab to protect the exit move. I think this route can be led with no big gear at all if you are willing to use that crack to the right.
Looking cozy in there.
