Tachyon is nice. Imori is pretty bomber and I personally prefer it due to the larger diameter and better hand (grip). OP 8mm hitch works very well with either rope. 7 coils.
Cool, Nick. Yeah, I found that more wraps with the OP 8mm was nice since the supple characteristics allowed it to grab more reliably without being so tight that it would sacrifice slack tending.
I haven't tried every climb line/hitch cord combination, of course, but that OP 8mm was my fav by a long shot.
Funny how I was under a different understanding of tying a hitch, when I actually thought I was holding true to original terminology.
My previous understanding was that if you're tying a hitch with a closed loop of line (or a large eye on something like a footlock loop), you'd get two coils for every wrap, because it's doubled line. A girth hitch would be 2 coils, etc...
I went back to 'On Rope' again, and there is actually a discrepancy between all this on pages 52 and 53.
Sorry for the derail, I just get into this kinda stuff.
Oceans, trust me I wasn't hassling you about semantics, if you knew me you would know I am far from anal about such stuff. I was merely commenting about the 7 wraps. When I was developing the HH I tried many hitches and found the 5 wrap prussic to be my favorite. For me going to a 6 wrap was undesirable as it added greatly to the drag when ascending, however as stated I discounted OP because with a 5 wrap it didnt grab reliably. Perhaps I need to revisit it.
Obviously "Ropetek" has to make recommendations for a safe system. IMO 10mm beeline tied with a 5 wrap prussic with a 2" gap between the top of the HH and the bottom of the 4th coil when loaded with body weight, is a safe system as it will reliably grab every time. Interesting to see others findings as long as they take responsibility for their actions...
i havent switched hitch cords yet. ive just been running the system as instructed with a six wrap prussic. was a bit grabby on and less smooth on the tachyon. the poison ivy was as smooth as glass. i did notice a bit to much grab on on ascent and slack tending though. ill try a five wrap today
My brother was here for chrismtas and showed me how he typically ascends on a HH. He uses a futura for one hand and grabs a biner under the futura with the other hand(or sometimes just the futura). (Leg loop on futura and pantine).
My first impression was I like the position better than what I had been doing, more upright. The biner under the futura seems slick, great position for other hand.
I revisited the 8mm OP with Imori with 7 wraps and yes to my surprise it works well. Wonder if having 7 wraps as opposed to 5 will prolong the cordage life???

Light weight, simple, safe and efficient...thank you Hitch Hiker.

Was it similar to this?

Yes. I had to actually try it to understand how nice the wrist positioning is. They key was the futura, as opposed to the position of say a petzl handled ascender.
I might buy a futura myself, but I was having problems a couple days ago with a borrowed futura not consistently grabbing on some HTP once up a ways. Very repeatable and was not jammed with crud, my hand was not touching cam, etc.
I tried to reproduce the problem for demonstration purposed yesterday hanging on the same rope in the shop and couldn't.

You're not alone with that one. I've had that happen with a futura and others have posted the same.
The best advice I have is to give the cam a light squeeze with your thumb before you load it. You can also try giving the whole futura a slight tilt before you load it.
It may seem cumbersome to do either of those things at first but it they're really just small motions that become muscle memory quickly.
