The 5 Large Divot Jugs are large and comfortable. They are an excellent choice for the beginner on vertical walls.
As the wall gets steeper, the Divot design starts to show its positive attributes. The divot creates a location for your thumb so you can engage the hold more by pinching it. Though not true pinches, they certainly feel like them when in steep terrain.
Expect V0 on vertical walls and V2 on 45-degree walls.
