Fluffy (mohair and similar) yarn

[aedifica]

I've done a couple of shawls in sockweight yarn now, and I'm thinking I'd like to make one with laceweight yarn next. It turns out my mental image of laceweight yarn is the fluffy stuff, mohair and the like (for example this stuff), because when I looked at non-fluffy laceweight yarn something inside me was saying "that's not right!"

I've never worked with that kind of yarn before. Is it easy or hard to work with? Does it require special care?
