Valdotain Tresse - cord length required

[sime42]

What length of cord do I need to start with to make myself a V.T. friction hitch, (to be used with the hitch climber)?

 

I'm using 8mm ocean polyester on a Yale XTC climbing line. I'll be tying my own eyes on the cord, probably with a Buntline knot. Aiming to start off with a 4 wraps, 4 twists config, as recommended by Treemagineers.

 

Any ball park figures for length initially? Id rather cut off a section of O.P. that's slightly too long than too short. (I don't mind trimming a few inches off the end of the cord, whereas I'd be pissed if I have to lose the whole lot if it's too short).

I usually buy it in 3m lengths to give me two bits of cord,  or multiples of 3.

 

I find that 1.5m is slightly too long, but allows a bit of adjustment of cord length and then cut the final few inches off when happy with it. That's for a sporty 3/2 hitch, so you may end up using the full 1.5m but should be enough.

Been a while since I used the vt but I think I used to use 120cm length for a

3/2 vt

What do you climb on these days Steve? I seem to recall you didn't take to srt, you still on a hitch?

Cheers Jrose. That was exactly what I was looking for.
I'm coming from a Distal Hitch;- is a 4/4 VT going to feel more or less sporty? If the latter then maybe I'll try a lower config.
