Oh yes. Yesterday, I spent quite a few hours trying different rope/hitch combos. I think for my weight (210 with gear), I preferred a 24 strand DB climb line between 11.5mm~12.0mm and an 8mm prisik wrapped 7 times.
My hand needs to learn to tend the hitch only since it never seems to bind up. In DdRT, I would grab the line above the hitch with my entire hand and pull down until my pinky finger opened the hitch, squeezing to add friction. With the HH, I find I can simply hold the hitch alone, which makes more coils work for me so far.
Like the RW (which I LOVE), it seems the hitch will have a great life expectancy with the HH.
Did a few +30' bombing swings and felt nice control.
I would like to see the HH side plates rounded...something like a Gri-Gri, but perhaps not so much (more like a HC pulley). This would help in fairleading when controlling the hitch with one hand and tending below the system with another.
