Hard to comment on the grade; I botched the sequence around the second bolt by going too low, then I botched the sequence just after the crux by heading straight up, downclimbed, grunted a bit, and finally headed out left through the finish. feet are decent for the crux, quite poor thereafter, but I can hardly say I found the optimal solution!
This is a must try if you're doing some climbing at the adjacent Gypsy Wall. The exposure was the best part of it. Def a future classic. I gave it a 5.10c rating because the two moves at the crux have great feet and after you figure out the move you'll see why I gave it a lower 10c rating.
