I bought one set of Denise's at regular price, and then found a lower priced used set. Because I knew I wanted to use 2 circs for lots of things. And I do (using them right now). I love the 2 circs method.
Though, to be fair, if I had a some longer cables, I wouldn't have a problem using the Options needles for magic loop. But, with 2 sets already, I certainly can't see myself getting an Options set.
(Though I do still want to get a set of the rainbow ones that Amy colored. :inlove: :inlove: :inlove: )
I haven't had a problem of knitting onto the wrong needle. :shrug:
