The Torque Nut shape fits well in normal crack placements, but they have the extra advantage of working extremely well when placed in a camming position.
The wire gives you more control for placing it above your head. When racked they will hang neatly off your harness without getting in the way. Just 4 do the work of 6 old-school hexes and because of their offset shapes, they fit into a multitude of crack scenarios.
