In reply to Mr. Lee:
Maybe its best used for winter climbing, the kind of conditions where you want to put something in a parallel or slightly flaring placement, but it's too icy for a cam and not going to take a hex?
While we're on the subject of tri-cams, I'd love for them to increase the passive strength of the little black one (the one smaller than the pink), or at the very least - give it the dyneema treatment.
Similar I don't get why they have two different tri-cam updates - there's the tri-cam evo, which gives you a 3rd placement option (akin to a sideways nut), and then the dyneema slung ones, which increase the strength somewhat. Why not combine both together? I'd buy a new set...
