    Or if you live next to a major army installation, ask any soldier to get you some parachute cord.

    Better still, if you know anybody doing major goldline replacement, ask for a scrap piece about six feet long.

    That would explain the change at Ginnie. Could do several scooters with what was removed past the Hinkle

    Hadn't thought about parachute cord, I'll have to get that.

    I would think a more static cord would be better than a thin dynamic cord like 550 paracord. I've never tried paracord, got to bet the scooter would feel like a yo-yo in you hand when you hit the trigger. I've always used 4mm climbing rope or some BS camping cordage that they sell at Ginnie.

    I haven't heard that story, but Wayne showed me the knot, as well. He called it a Midshipman's Hitch, which is just an alternate name for the same or similar knots.

    Prusik, Taut-line hitch, midshipman's hitch and others are all types of friction hitches, a knot that uses friction to hold its place on another rope yet can still be adjusted. A lot of people seem to use Prusik as an umbrella term for most kinds of friction hitches.

    We had a big spool of parachute cord at the shop before we moved - I haven't seen it since. More than half of our instructors are military.

    The parachute cord I have and the gold line I have seem to be identical except for color.

    I agree, that's why I use 4mm accessory cord. Most of the 7-strand 550 para-cord available today is only 1/8" diameter and it does not hold a Prusik knot well.

    I use a bowline with a lock-knot on both sides of the scooter.

    Why use a sliding knot at all?

    Mine is set up like a daisy chain. It has overhand knots about every 3 inches or so. It’s really easy to change which link you’re clipped into on the fly. Takes about 2 seconds. No slipping...ever, per the design. The problem w/ a prussic is that they release when not under tension. So you get it the way you want it, let go of the trigger, the knot releases, again, per design, you hit the trigger again and it slips.

    It depends in part on how tightly you dress the knot and in part on the rope you use, with with a cord with enough friction (wet does not help here) and a knot that is properly dressed and snug, I have not had this issue.
