Which 7mm/8mm cordage for prusik?

[tpcollins]

I'm leaning towards a polyester sheath but trying to sort out the claims from manufactures is a bit tough, so for actual users I'd like to know what works best?

 

Some of the cordage I see at REI seems a bit stiffer than they should be. Thanks.

For starters 7mm/8mm cord is too large of a diameter for a prusik knot. You want 5mm. As for the sheath to be honest I have never worried about it. I have always bought cord with a nylon sheath.

Agree with the above. Buy 5mm or 6mm with whatever seems to be the most supple. Some tends to be stiffer than others, so just go by feel. I used to use 6mm but had a bad habit of using them for rappel anchors. Now I use 5mm so I'm less inclined to do that unless I'm in dire straights.

You need enough of a diameter difference between prussik and rope for ithe prussik to grab. Most people use 8 or 9mm climbing ropes so I go for 5mm prussiks. Stiff or supple, it will still grab at that thickness but the supple ones are easier to tie and wrap.

Concur with all of the above. I use 5mm. The stuff from REI. It seems kinda stiff as you say. I got some once from an online retailer and it felt the same. I don't care enough about it to drive all over town and feel up different cords so I just keep using the same stuff. Don't over-think it.

I never have used the stiffer cord but have been told it's a little easier to slide when not loaded and releases a bit easier after being loaded.

The Dyneema tech cord can melt when used for prussik. Just use regular static cord.
