You only need 1 and still use a cord/sling for the second one. Now lighter Gri Gri 2 are actually pretty nice to carry on multi-pitch climbs (not in the mountains of course, but at a crag).

Have you prusiked on a wet rope in a rain or on iced up rope?

True. I also find that I have to readjust the number of wraps on my autoblock (for rappels) depending on how skinny/fat the rope is (I'm used to skinny so I tend to overwrap) I suspect that would be the case for ascending too, then you'll have to readjust the length of the foot sling too, no?
