I've heard a lot about this yarn, so I got a couple skeins off eBay. Seems to work well with the "Magic Loop" technique.
Unusual for me: I'm knitting from the top down. I thought this yarn might be good for Kathleen Hubbard's Aran-Braid Socks, but the subtle color pattern was obscuring the braid. So I ripped it out and am trying the "Vine Lace Socks" from Socks Socks Socks. I've been getting a lot of mileage out of that book recently.
