My first trip to Black Feather Canyon and I tried to on-sight this route. Super tough move in the middle, left sloper that you lose grip on if you hang at all. Have to make it fast to clip the next bolt. Easy to cheat over left, that is not the intent though. I see the guidebook has this as 5.10d and RC has it as 5.11a, which I agree with....even though normally I go the other way in the Canadian Rockies.
