/ 6-7mm cord, abbing on it?
Abbed off 6mm+9mm, 7mm+8.5mm, 5mm+5mm .
Be careful with differential rope slippage, slashing thin ropes and rope stretch.
Ideally practice with a top rope first.
Getting the ideal amount of friction takes practice.
If possible I put both ropes thro the same hole in the plate and if the rope is very thin an additional friction hitch after or before the plate.
On a 20m free ab on the double 5mm, an in line Italian hitch and ATC worked very well, but otherwise felt on the limit of acceptability for safety, not for the faint hearted. I still prefer double 10mm.
I use a 6mm Kevelar/spectre quite often for abseiling. Use a small belay device and a 4mm prusick to get extra friction. Expect it to be slicker than a normal rope.
'an in line Italian hitch and ATC'
never heard that one before - Like
What about the often mentioned but I've never tried or seen 'Monster Munter'? Supposed to twist the ropes less than a normal munter, but provides additional braking force...
Just looked it up. Could be ideal.
Indeed, with the note that presumably the carabiner should be the other way round to stop the brake line rubbing on the screwgate? :)
I use a 6mm line as an escape rope for soloing on relatively easy alpine routes, and I've used it a couple times with no issue abbing with just the ATC. But that was on low-angled ground where most of my weight was still on my feet.
How does the in line munter work? Do you extend one on a sling or something? Does it matter what order you use them?
Noticed that after posting.
Might be hard to tie it the other way.
Again it needs a practice trial.
