DMM 3CUs and 4CUs

Summary: The most noticeable thing about the DMM 3CUs and 4CUs are their bright colors, which makes picking the correct size from a crowded rack a breeze. Each unit's cam lobes, trigger bar, and thumb bar are anodized to match, and, yes, the doubled sling blends right in too. The trigger bar allows for a bit of independent cam manipulation -- rare on a U-stem unit. Another unique feature are the cam lobes (with integrated cam stops), which are wide when fully retracted and taper to a more standard width near the end of their range. When the cam is placed tightly, there is more cam surface against the rock for greater grip -- great for parallel cracks, but if the crack is flared or irregular the cams will sit awkwardly. Another drawback is the trigger bar's tendency to slide up the trigger wires toward the head. The extra step of pulling the trigger back into position is easy, but a burden on pumpy routes.
Pros: Extendable sling; trigger bar allows for some independent cam action; great color coding; cam stops; light.
Cons: Poor performance in flared or awkward placements; trigger bar slides down.
