I fell in love with this Set#2 the first time I climbed on them. I took two sets and set a boulder problem on a 20-degree angles wall, and once I "settled" on to the holds, searching for just the right feel, I found the crimps followed the contour of my hand in a comfortable way. This is the kind of crimp that the intermediate to expert level can run laps on.
The incut is about 3/8" deep, and there is a contoured lip that is surprisingly comfortable for a crimp.
Set #2 is harder than Set #1 and easier than Set #3 and Set #4.
On a vertical wall, expect V1+ feeling crimps. Again, this is a great choice for the beginner.
On a 20-degree wall, expect V2 feeling crimps.
On a 45-degree wall, expect V9 feeling crimps.
