In reply to beardy mike:
> By comparison nearly all hydraulically crimped terminations are crimped all the way to the end of the ferrule which means there is a bending point at the same location as a cable in a prestressed condition. Nearly all cams which use a single short strand of cable suffer from failure due to flexure at the joint.
I'll back that up with personal experience! Was out climbing without someone once and must have been idly fiddling with one of their cams when I noticed that about half the strands of the wire were broken exactly where it exited the plastic sheath and entered the rigid tube leading to the axel. It was such a fluke occurrence that I was even looking really and I was shocked. Ever since, I have regularly checked my own cams for broken wires in this location!
In reply to the OP:
I once had a couple of zeros but I despised them most of all the microcams I've ever used (even more than C3s which I also dislike but for different reasons). The grey one was admittedly just too small but the yellow one was the same size as a 00 friend and every single time I played with both the Z4 and the 00 friend, I ALWAYS felt happier with the friend. The Z4 just wobbles about so much and feels so insubstantial and it felt much trickier to really ram it into an overcammed little constriction because of this feature (and the smaller the cam, the more overcammed you want it innit!). I fell on the 00 friend but never got brave enough to fall on the Z4.
