If a flat item on a single circular is too confusing you can treat Options as 2 straight cabled needles. That's why they include 4 cables in 2 sizes and stoppers.
They're only circulars when you have 2 needles on one cable
I imagine Options would be much better than my 16" bamboo circular but the only issue I've found was casting on and having the cast on stitches tighten to the cable.
But it works itself right when they get back on the needle so it's more of an annoyance than a problem.
I'm guessing it's really annoying depending on what cast on you use judging from when I've used a cabled Tunisian crochet hook.
I plan on getting Options eventually. It's just not high on my list at the moment.
