Congrats! It's one of those things that definitely looks really intimidating but once you get over the "I need more hands" stage it's not so bad. Definitely a gamechanger for second sock syndrome!
It's not that bad if you have a nice cable without memory (I use chiagoo). It takes a bit of practice but once you get the hang of it ...it's great. I've been obsessed with socks and mittens lately. This technique makes perfectly matched pairs with less row counting and tension differences.
