comment How does cam strength change with the retraction angle?
@Felix: Good question! I would refer to a tipped out cam as fully retracted, so I guess retraction?

comment Knot for Joining the ropes of different thicknesses
Good point, by "sensible" I mean two ropes rated for climbing (singles, doubles or twins). Look at tests 15 and 17 for 16 data-points with ropes of different diameter. I don't personally believe there is a right way or a wrong way to tie the EDK (after the first inversion the small rope would have to roll over the big rope, and the knot gets tighter with every inversion.) As long it is dressed properly and you have enough tail, I haven't heard of any accidents resulting in its use, but I guess all of this is mute, since the OP didn't ask about rappelling. Should we continue this in chat?

comment Knot for Joining the ropes of different thicknesses
@BenCrowell: For activities related to rappelling (where the profile of the knot matters) I do advocate using the overhand with ropes that are commonly used for climbing. There is an interesting blog article based on some test-data the author linked to at the end of the article. I haven't heard of anything going wrong with ropes that have sensible differences in diameter, but if you know of any incidences or testing that show the contrary, please share!
