Hi,
I am the owner of the Ultralight Camalots for which the trigger wires detach. It has happened three times in my pack, but now twice on route, which is less forgivable.
The weight saving on the two larger sizes is significant. But I suspect they will be less robust than the C4. I have come up with a fix for the trigger wires, but whilst I am hugely impressed by some elements of the engineering on the Ultralights, BD do seem to have dropped the ball on something pretty basic. The issue is starting to be voiced on some US sites also.
I wouldn't get the smaller sizes myself, as for me the expected lower robustness would outweigh the benefits. That's just my guess, time will tell. Hopefully ultralight cam larger sizes + rubber bungs + glue = awesome.
