Okay, I'll admit, I was a bit skeptical of these shapes at first. They look too simple, and I didn't think they could be versatile enough for my gym. Upon closer inspection, each side/corner of these volumes has a different swoop. Some sides are more positive, while others are less so. The holds are a bit too easy on vertical terrain (good for V0-V2), but as soon as you start setting on a steeper angle, they really come to life.
