I am currently using this on the little roof that tops out my 35 degree wall. You can hang one-handed from it on a roof. The deeper pocket is three pads deep and four fingers wide, with a rounded, in-cut lip. The shallower side, when on the roof, gives you a sloping 1.5 pad, four-finger pocket. Pinch it, match it, or take a flying leap for the big slot. Makes a great finish hold for a boulder built on one of the 5 simple pockets sets.
