I got this set in addition to the steep wall 60 pack and 12 large limestone jugs. These are great for either making a v0-v1 route on that wall, or as I use them for, putting a rest point after a series of hard moves.
The texture on the outside is really nice, and they all have a good spot for your thumb, to get extra grip. The inside texture was a little rough on my hands, as I was often throwing for these, so I followed the advice on the Atomik site and lightly sanded the inside down a little, and now it is perfect.
Highly recommend for a 45 degree wall to make it accessible to more climbers.
