Circular for me baby! Knitting with straights is too awkard for me and wastes space. I love plopping all the stitches on a circ and being able to knit with my elbows relaxed. I LOOOVEE my Options, and I still use my Addis too here and there.
It's funny, when I first started I thought circs were awkward and avoided them. Eventually I changed my mind (Oh yeah--and bought some non crappy circs
That might have helped).
