Magic loop definitely. Really, no need to bother with the 2-circs. I started using circs because I always dropped a dp.. always. And 2 circs - it happened, too. Magic Loop is the only way. I have done 2 socks on one Magic loop. It works, but I find it terribly fiddlely. Except in rare circumstances, I'd prefer to just make the 2 socks separately, taking really good notes along the way. Chinese waitress... very good, very finished looking. stretchy. It gives a double-chain appearance, so it is good for when you want a smooth-looking cast on. Not my choice for socks. I like Jenny's super stretchy cast on (the one that she describes a sea lions lying next to each other on the beach), or Channel Islands for a picot type look.
