Single line accessory cord questions

#1
Hi guys

I have some questions about single rope ascension-descension technique :

1- what do you think about using kevlar accessory cord 5.5mm on a 10.2 mm with vt hitch or diestel hitch, could it work or a bigger accessory cord diam is needed?

2- on a single line is possible to use vt tresse or this kind of knot works well only in srt closed system?

Thanks for feedback!

Your going to need larger cordage regardless, preferably something heat resistant. While there are a few hitches that allow descent on a single rope, your best bet is a way to add friction to take some load off the hitch. I.e. ropewrench, figure8, munter, etc.

I wouldn't use less than 8 mil cordage. And not accessory cord, but heat resistant hitch cordage.

And you should definitely have a rope wrench or some way of adding friction. Otherwise you will have no fun
