Pros Light, flexible stem, awesome in pin scarsSuper light, durable, easy to place while free climbing, great rangeWide range per unit, light, rigid when placing but flexible when placed, narrow head width, thumb loop, smallest unit currently madeDurable, wide rangeFantastic design, smallest cam in the world, great strength, extendable sling, flexible stem
Cons Concerning reports about quality and customer serviceExpensive, need for potential early retirementNot the most affordable, smaller units lack double axle and aren’t as smooth, trigger wires can’t be replaced at homeHeavy compared to Ultralight C4s and MetoliusNot available in offset sizes, smaller individual cam range, action on smaller cams not as smooth as larger cams
Bottom Line These narrow headed cams work well in Yosemite finger cracksThese cams are awesome for long Yosemite free climbs and Indian Creek splittersA Top Pick for smaller sizes due to the widest range and incredible ease of useThese are the most popular cams at Indian Creek due to their great range and durabilityWorthy of our Top Pick for small cams due to their excellent design and performance
