I bought these for an overhanging wall I made, and the steepest two are nearly unusable, but on a vert wall they would be fantastic. Sans the angle, each hold is identical, making it possible to really fine-tune the difficulty of a problem if you want to swap out a specific hold on a problem with a different hold. Note that these are too small to be the kind of sloper you can wrap your whole hand around, but still require the same technical footwork and body positioning that any sloper does.
