I'm sitting here playing with my new accessory cord, and screwing around with hitches. My blue/white cord will not work with a tautline at all. I can snug it up and get it to work once, but as soon as I slide it, it loosens and won't grab. It works in the black cord. The blue/white is a little too stiff and slippery. The blakes works great in both cords. The question is did the blakes solve a common problem at the time of release, or was it just a variation on theme, and a matter of personal choice?
