Has anyone had any experience of the small size DMM Demon cam's (The Blue 0, Red 0.5) holding ability, given that the surface is quite heavily serrated compared to most small cams that I've seen? They seem like the best choice for a small cam given the strength, but there doesn't seem to be much area for them to hold with!

In reply to Bryn_F:

If the rock was perfectly smooth, then sure, more grooves would mean less friction. However, in most cases (and depending on your type of rock), the grooves are likely to help the cam to grip into the rock better.

In reply to Bryn_F:

Agree with matt above that grooves there to add friction not reduce it. I've fallen on both sizes you refer to and had no issues. Of course, as with any pro, depends how well you place em.

In reply to Bryn_F:

The more metal in contact with rock, the more holding power. So grooves not always necessarily add more grip...

Maybe have a look at new dragons as lobe surface has been redesigned for this reason.

Probably not true for all rock types and placements.

The science and understanding of micro and macro friction are very complex and probably incomplete.

Any cam design is a compromise for varying rock types and placements.

A cynical view is that they are probably just designed to look "right" and maximise sales Though since the OP asked the question possibly not.

I think you are over thinking it. DMM know what they are doing.
