TWS is a bolted arÍte with some super cool crystal structures and fun moves. The crux come down low, just before and then immediately after you cross the arÍte to the left face. The route unfortunately feels a little forced or dare I say contrived for the rest of the way due to big holds and the bordering route on the left, especially at the 2nd to last bolt (harder straight up, easier out left). Nonetheless, the climbing is on fantastic crystals and will get you psyched! As for the rating, IMO, if Beetlejuice on Hornet's Nest is 12-, TWS is 11+...
On the west edge/arÍte of the Chopping Block...I found the best belay stance directly under the 1st bolt, a super short scramble straight up.
