I like the flexibility of these cams. I picked up the Z3 and the Z4... I would recommend all of the sizes up from the Z3 for trad. All in all, I would say that I like them as much as aliens, but they are more flexible. They just don't feel as solid though, so it's a bit of a trade off in my opinion. However, I took my first real fall on trad on a Z6, and it held beautifully. 15 ft fall, 45 feet of rope out in good granite. No deformation, etc, on cam.
