There's at least one cam in this Wild Country Friend Set that would fit in a crack that suits your hand-jam perfectly. One might feel too small, and the other too large--or some other combination--but at least one will slide into a crack as perfectly as your mitt. Given Wild Country was the first company to sell the original camming device, you can rest assured that they've had the longest to research an ideal construction. The 13. 75 camming angle is the ideal angle for secure placements, and the high-friction faces keep the cam positioned exactly how you want it. The Dyneema sling is extendable so you can leave your alpine draws at home.
