I recently cleaned this route well after putting up Muscle Crow. It might be a little harder at the upper crux but the climbing is way cleaner and better. I'd give it 11a.
An excellent route. I would say 11a is reasonable. If your friends walk up to this thing and tell you it's an easy 5.10a warmup... don't believe them. Unless you think 11a is an easy warmup that is.
