The cable cast on seems plenty stretchy to me and not nearly as futzy. I'm not good at guesstimating the length of yarn needed for long-tail cast on and I hate ending up just a little short or waaaaaaaaaaay too long. Sometimes I think just because something is more complicated people think it's better.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
