My existing footloop is made from New England Ropes 5mm "Tech cord," which is a Technora core and polyester sheath.
I'm retying my footloop, but all I have at the house is Bluewater 5.5mm "Titan cord," which is a Dyneema core and nylon sheath.
Since a footloop isn't a load-bearing application, and these are both essentially zero-stretch cords, I know I'm splitting hairs... but do folks have a preference? The only complaints I have about the Tech cord are a relatively-stiff hand when compared to regular accessory cord (or even the length of 5mm pure Spectra cord I used to have), and the fact that you can't melt the stuff with a hot knife.
