Disclaimer: I've never used a hitch hiker. While the concept seems brilliant,, knotting the ends of the hitch cord through the dog bone seems to be the least elegant part of the hitch hiker design. Although it does offer the benefit of eliminating the need for eye-to-eye hitch cords, tying the stopper knot every time seems slightly cumbersome. Would replacing the dog bone with, for instance, a load bearing quick release pin be an improvement? The pin would be inserted through the eyes of an eye-to-eye hitch cord. I envision one similar to those used on Gibbs. A means of securing the hitch cord eye to the tip end of the QR pin would be required, such as a fender washer, which could be tethered to the body of the HH.
Alternatively, maybe one end of the dogbone could be slotted and have some type of gate or pin that would allow the hitch cord (with a pre-tied stopper knot) to be inserted and securely retained, eliminating the need to tie it every time.
