I used these on a 20 degree wall. I have never used mono pockets before and expected them to be very painful, but they don't hurt my fingers at all and the texture is smooth but grippy. I really like the two deeper pockets, I feel I can really pull hard on one finger. The shallow pocket is much more difficult, but fun! I imagine you could use these to set anything from V2-V10+ depending on how much focus is on the mono pull.
