I have these on a 40 degree wall.
These are really cool and unique holds for a home wall that add an extra dimension of creativity to setting. I currently have them all set as a single route doing a rising traverse and it's the coolest route on the wall. They'll work well with others hold types for more varied routes too. Two are quite long at well over 12", two are about 12", and one is about 8". They all have variable depth along the length and a few dimples for some thumb action. Grip depth is a little less than what I'd call a jug on my overhanging wall, but on a vertical or slight overhang they would be like mini ledges or dikes. For me theyre a little challenging, but I could set them to be easy if I chose to take advantage of the optimal orientations. Super versatile and fun hold set, easily among my favorite holds on my wall.
