What are the different materials for ski climbing skins and advantages to each?

Question

I'm using mohair climbing skins right now but I've heard of other materials. What others are there and how do they compare to mohair?

Answer 1

Mohair is lighter and glides better than nylon, but does not grip the snow as well going uphill as nylon does.

I have used rubber skins before, which will really climb steep stuff, won't glide very well at all, and weigh a ton.
