I'm making socks with Crystal Palace Panda Wool right now. It is a blend of 51% bamboo, 39% wool & 10% nylon.
They are working up nicely on size 1 or 2 needles (I forget which I'm using). The sock pattern is from the book Socks, Socks, Socks - it's an all over reversible cable pattern.
I can't really answer most of your questions as they aren't done yet so I don't know how they will wear. They feel like a nice tight sock fabric so I think they will wear well.
