I purchased these knowing that they would be super hard. I use them on my 40° wall for training endurance and hard sit starts. These easily fall into the latter category. Rotated vertically I can hold them for the start and then bump a short distance to a mini jug. If I have one good handhold then I can use the other to start on one or transition into and out of it. I am a V4 climber, but pinch strength varies so much in the community I find these hard to rate. Probably V5-6 oriented vertically and V3-4 horizontal for the easy piece. The smallest two are way gnarly and beyond my scope as a V4 climber. I like this set because two sets
can be "mirrored". They are similar enough I can use them to make a right hand and left hand version of a route on a small wall. Perfect for training. I want to find a way to use these for pinch training in my home gym with some creative cobbling.
