More circular knitting

My favorite way to do circular knitting is with 2 small circular needles. I think it is the easiest, however I use magic loop - one 40 inch circular needle - the most.   This way I only need 1 circular needle.  I have found that a really flexible cord is super important with magic loop.   I hear Knitpicks has great circular needles as does yarn.com.   I have gotten some OK ones from Joann Fabrics.
