Just to add to the confusion on this (i.e. more choices), ZPacks sells a variety of small stuff. They have a Z-Line Spectra cord in 1.25mm or 1.5mm. They also have a Z-Line Slick Dyneema cord (probably Zing-it), but they also have it in 1.4mm.

Hope that makes the decision harder.
I can't make up my mind on which I want either....
