I got these for my completely horizontal roof, hoping to make some easy roof jug haul warm-ups. They're actual a bit shallow for what I'd consider to be a roof jug, and find myself relying more on the pinch with the divot. The red and lime green holds in the first picture are definitely quite shallow and more aggressively sloped (for a roof jug). If you're building a horizontal roof, I'd consider something larger.
For my 40 degree wall, these are total bomber jugs :)
Great construction / texture / quality, fast turn-around and shipping otherwise.
