The JRB hitches became very tight and hard to move with both Mammut and ultra tech 8mm ropes with beal and coppa for cords.What rope were you running for your jrb system that they were binding?

Did you try it on a bigger rope? You got me concerned now. I'm gonna use either my predator rope or that blue moon I ordered. 11mm. But I weigh a little more than you, and worried about them jamming now. As far as the cord, is the lengths the same? If I tie to one should I be able to tie the other? Or will I be short.. I ordered 20 of cord.The JRB hitches became very tight and hard to move with both Mammut and ultra tech 8mm ropes with beal and coppa for cords.
I wouldn’t worry. When you get your stuff in I would try it out for yourself and make a call on whether it meets your needs or not. You will also have the option of using other hitches it you don’t like one. As far as cord I would cut the amount that John suggests on his website. 20’ should be plenty to make a few hitches.Did you try it on a bigger rope? You got me concerned now.

Right and I think this is what the JRB hitch try’s to accomplish as well. As for the square knots below other hitches it has crossed my mind to try out. It could be a fun experiment. For a rope climbing, having those hitches grab instantly is a huge nice to have.I think the bottom couple square knots are just there to produce the self tending capability. Otherwise it looks similar to like a double Michoacán with three over, top leg comes back under two wraps. This is why it seems to grab before all the slack is taken up, the top 3 wraps should stay fairly tight like a traditional prusik, the lower leg being tucked will provide a pretty smooth adjustment but the square knots are there solely to provide the tenderless self tend. You could tie a distel or schwabisch with two square knots underneath it and probably get the same functionality. Or use a VT which is not of the strongest holding hitches there is and it’s easy to adjust if you want a hitch cord that is that long and takes up that much space
only I think with a schwabisch or distel, that a single or double “cobra weave” aka square knot would provide plenty of push back to get those hitches to self ascend.

That was kind of what I was thinking. I haven’t tried the synergy x simply because of the amount of chord it requires. Thanks for the input @Brocky it’s great to have a hitch aficionado on here to referenceThe wraps do the major holding, with what happens below them is meant to add some additional friction, this allows for easy release. There has to be enough in the series to take enough weight off of the wraps, the multiply bends also keep slack from moving within the hitch.The Sticht and others also work on this principle.

The Synergy X is similar, but seems to tend easier tied this way. Both hitches should be tied fairly tight to prevent too much separating when loaded.
Wraps on top are the simplest option, but any hitch on top can be made easier to release by adding the hitching series below.
Two other options that require less cord but need a ring. Both adjust and self tend, with options to make it easier.

Cmon man, it’a the Sticht hitch! Aka possibly one of @Brocky s favorite hitches?What’s the name of this hitch?

Thought about it but haven’t tried it yet. Also the ring size used matters. If you use too big of a ring it is possible to pull through and break down the hitch. Should we start a Sticht hitch specific thread, or however you spell it?The parts of the rings not in contact with the rope could be wrapped to silence them?
Thanks for the info4 1/2-5’ , I need to make some longer than the 48-50” ones I now have.
