Not sure from the description if I did this one or not. Do you traverse under the arch and top out directly on the other side? Or are you supposed to climb to the far left (when looking from the ground).
Well, in lieu of an answer, I started this route at the base of Frosted Flakes, climbed through the overhang using reasonable holds and marginal feet, and rolled around the other side for the top out. Once I got to the top, I traversed directly under the roof, which is my interpretation of the climb. I definitely thought it was worth the effort. The rock is good and the beta at the top was fun to work out. Felt more like V4 to me. Check this one out!
Sorry for the lack of a response. You did it the same way I have. I would take the V4, Merc and I did this in the middle of a summer, and those top slopers felt a little greasy, very fun climb. Did you try the other climb?
