Comments about Koll�ge Yarns K-Kable 16" Square Circular Needles:

Unlike some other raters, I LOVE these needles! I am somewhat clumsy and use circular needles for almost all my projects (even when not knitting "in the round"), except when double pointed are needed. Often the cable is made of plastic that gets somewhat twisted and won't stay straight for long even when you use hot water, which drives me batty!

I do very much like the way the cable feels in these needles (at least in the small size, I used 16", size 3) and that it doesn't twist up. I have not completed the project yet however (a hat with fine yarn, a challenge for me).

I'd say try for yourself and see what you think. I may order one of each type of the square ones, just to test. Previously I had used Audi turbo and another brand in bamboo, with some pros and cons for each... but the twisting of cables in the longer sizes of these drives me nuts.
