I am currently using these on my 35 degree wall, mostly as footholds paired with the 5 Medium Golfus Edges (Steep Wall). I am using the largest one as a starting handhold at this angle. On a 35 degree wall, the combination of the Steep and Vertical sets forces precise footwork and solid core tension to hold on. As steep wall footholds, the texture combined with the Golfus dimples is just grippy enough to hold tension, as long as you stay focused. I might move these onto less steep terrain to try as handholds, but I am having fun with them as technical steep wall feet for now. I highly recommend both this and the Steep Wall sets.
