Ultimate Doom

Start as for Chaos Roof, but instead of heading left throw out right to some blind slaps for crimps, working your way into the undercuts that mark the start of Doom. Finish up Doom.The direct version, which goes at low end V11 (ish), adds a hard move by eliminating the left-hand flake that Ultimate Doom normally finishes on. Instead of going left to a crimp and bumping to a jug from the undercuts, go up and right to a good crimp, left to a thin crimp, and up and right to a good flake. Top out. 

Start as for Chaos Roof and head right, finish on Doom.
