The 12 Steep Wall Brain Coral Crimps are an excellent choice for steep walls as they fill the grade gap between V2 and V5. The lip of the incut is about 1/2" thick, and they offer a one and half pad comfortable incut. You can run tendon-friendly power endurance laps on them.
The incut is quite steep, so no matter how steep your wall gets, they will still yield an incut. On a vertical wall through to about a 20-degree overhanging wall, they will feel like a V1 mini jug. On a 45 degree wall, the incut is still present, so expect a V3 feeling hold.
On a wall that is 55 degrees overhanging, the incut is horizontal to the ground, which brings you into the V6 crimp range.
These holds perform as crimpers and on all steep angles except for a roof section.
