My understanding about having a 16" cable is that the interchangeable tips are too long to comfortably work on that short a cable. The fixed 16" circulars have shorter tips.
I also love my Harmonys. I had a project on circulars when my needles came and immediately switched over, it was such a relief to my hands and wrists. The stiffer cable on my old needles was so difficult to work with I almost gave up on the sweater. The harmonys made it so much easier, it was like night and day.
I would like to eventually replace all my dpns with KP products as well as my smaller size circulars.
