I started climbing last year. This route was the 5th route I tried, but the very first route I did not complete. Cold weather came in to ruin the climbing year. Myself and two friends have been climbing on indoor walls whenever we got the chance. Came back out to Hidden on the first pretty day that we could and started on warmup crack and the one to the left of it. After that we moved our ropes and set up for undercling fling. After some frustration and hardship, Finally I worked out the issue of no hand hold on right and got up to the undercling fling. There is a slight dyno that needs to take place, or you can fall and re-set your hands (wouldn't suggest this). Great climbing after the crux 9' up. I still don't think I have climbed enough to rate this properly, but a 5.7 seems about right/maybe high.
So, we did this route this weekend, and it seemed much more challenging than a 5.7. We started directly below a nub that was about 17 feet off the ground and found the handholds pretty tricky once you got about 9' up. Almost had to dyno to the huge nub that was just out of reach....were we missing something?
(to refine, we were just below the single bolt/tree above us)
