I have been corrected. Guilt Trip climbs the roof on the NW corner of Challenge Buttress. Climb up to the chains and continue up the face to the top of the buttress.
IMHO, this should have some stars. A classic, foot-dangling roof! And yes - this is the big roof with 2 bolts right on the lip. The arete to the left is 'Broken Thumb' (aka, NE Corner)

This route is just right of Tuff Enough. Two bolts with chain over the big roof. So, not really on the NW corner of the formation, IMHO.
Note: straight up, or, just slightly left of the bolts seems to be in the hard 5.10 range, whilst the right hand variation, 3 feet to the right of the bolts, seems to be in the hard 5.11 range (both options a bit of a one trick pony move). Both variations are followed by easier vertical terrain (5.9ish) and very good gear placements up and just slightly right, followed by a step up to the ledge and the anchor atop Tuff Enough. Gear options range from small TCU's up to #2 camalots (or equivalent) with emphasis on small to mid sized pieces (say, #1 TCU to .75 camalot).
