Wich tipe of rope for a harness

[edt]

Try to find something from climbing and hiking shops. For them it is lifesafing - so durability wise

climbers and hikers need a very specific type of rope for rapelling and climbing. They need to put in protection and then when a climber falls 100 feet down the rope must not absolutely take them to a dead stop, which is something dyneema does with very little stretch. Also they must be able to make knots, all kinds of knots, rapelling knots, ascending knots, belaying knots, and the knots must not weaken the rope. For these reasons, climbers typically stay away from dyneema and use 9mm (9mm fits their equipment) sheathed polyester, which doesn't slide very well at all. Dyneema for which is the strongest most durable, most abrasion resistant, UV resistant rope that's made today. Other materials like kevlar, or other synthetic materials might show a slightly higher abrasion resistant or strength but wear much faster than dyneema or spectra.

Sailing shops have the type of rope we want to use, not climbing shops. If you are abrading your 5mm dyneema too fast, then maybe think about switching your roller or friction ring to reduce abrasion. There's nothing better than the 5mm dyneema you're currently using.

5mm amsteel blue is about two times the strength of a 9mm climbing rope.

Climbing ropes are the best because they often have an outer coating made of polyamid which has to slide over rocks. Mine ist from Edelrid and lasts nearly forever.

isn't polyamid a type of nylon? Dyneema is more resistant to abrasiona and slippier. In fact it's difficult to knot dyneema and the knots on dyneema are known to slip, which is a disaster for a climber. It's possible it's not the material but the fact that you have a 9mm rope instead of a 5mm rope. Put a 9mm amsteel blue rope on there, that's a 17,600 pound rope, it will last until the sun goes out. By contrast 9mm climbing rope is around 3000-5000 pounds.

Ok but tubular webbing, for anchoring, has practically zero stretch and is very resistant to abrasion.

here's a cheap one:
