Kenny isn't lying when he says "sinister on steep." I knew it was a stretch getting these when we only have a 45 and 60, but there are enough good spots to make them work with some extra help from other holds. We have them set above the big granite pinch from Atomik, and they feel like V8/9 even with a locker heel hook on the pinch. Once they go on some volumes we built they will work like a dream in the 60 too. I only recommend these for people with relatively low angle walls, or anyone who wants to really get frustrated in the steeps. I love them so much already though.
