Love these little guys. They're usable on my home 45 deg wall. NOTE: I do prefer these for static moves mostly. There's not a lot of plastic around the screws, so on dynamic moves on overhanging terrain, they can flex a tag. Not noticeable on static moves; you will notice on big throws. It has never caused me to be spit off, however, and I've not had one break. If you want a beefier, affordable crimp option, I recommend Atomik's "10 Basic Split Crimps Set." Both sets fit anywhere and add a lot of variety in setting problems.
