In reply to MeMeMe:
I've got a C3, not had it very long though so only placed a couple of times. Thoughts so far:
- Narrow head width is great they go in securely to placements wider cams will not.
- Stiff springs definately seem to help prevent movement on the cams and are fine when placing, the stems don't bend during retraction.
- Lateral stiffness is spot on as they do flex enough for placements in vertical cracks where quite unusually they can't be aligned to the direction of fall (without damaging the cables) but allow the cams to be fiddled in to cracks nicely, the stems are quite bendy the other way which is also good for horizontal placements where this is commonly needed.
- So far the extra width on the central lobe hasn't been an issue but I can see it being so for some placements as it won't 'fit' the rock as nicely as two lobes would.
C3s seem to be a bit of a marmite cam depending if you are talking to someone that actually owns one IMO
