its not a load test certificate.
it can provide some information about thickness and breaking loads relation.

Having watched a LOT of videos on winch ropes and soft shackles, I'd easily accept that tech if I ever need a winch again. I really don't see many negatives.

Dyneema has an operating range of -40 to 70 deg`s. The winch brake in the drum generates more than that. Steel dissipates the brake heat generated Dyneema not. When switching to Dyneema it is crucial to install headguards on the rope to prevent degrading of the fibers.
You will never find me without Stroh or a 4x4 :D

in a defense of dyneema.
this is from 2 weeks ago.
5mm dyneema,winching 30 seconds, rest 3 minutes.
20 minutes total for 2 car lengths.

mahindra was pulled out while in neutral gear,as any torque applied to wheels made them slice a earth in front like a hoe.

I am curious. Did your wheel winch not work ?

*This is not recovery advice. Follow the usual safety guidelines, I like to experiment and this is my experience*

I want to dig this up, as I have had some more testing, product information, change of heart, ETC. So for anyone that cares.

Soft Shackles.
So my soft shackles I love. I have used them extensively for pulling and nothing wrong with them. I will always carry my 3/4" bow shackles next to my softies in my larger than normal recovery kit maybe for a scenario when there is something sharp but my softies are my go to. Softies also are a bit more flexible on where they can attach and how.

Pull strap
I have a 30m and 10m Dyneema rope that I am ready to replace my 5m and 10m pull straps with. Just for space, the pull straps take up half my crate and the 40m worth of dyneme takes up less space than the 15m of pull strap..

Winch
I feel a lot better with it than cable and it seems solid still. It has rubbed on some slight abrasive surfaces while taught and I dont see any problems yet. I am quite surprised on its resilience to damage on surfaces. I still prefer this for my winch line. Maybe the chafe sleeve will need to be replaced sometime as that is showing a bit of damage, about R1300 for the entire sleeve.

Winch Ring
NOPE. I will stick to my steel/ali snatch blocks. Winch rings with soft shackles just wont cut it, fight me :mrgreen: The heat generated on a hard winch melts the fibers and they start to give in. Only a tiny amount but I can just chuck that strap rather. There is a chafe sleeve that comes with them but I dont think they were designed with this in mind as they stick and twist up, twisting the entire shackle.

I did have to get my my snatch blocks machined for my rope. The things have(d) sharp corners obviously not caring for Dyneema and the groves are designed for a steel cable.

The bonus of rings and soft shackles is that they tuck in nicely into a kit size wise and weigh a fraction of a block and cable.
Maybe for someone who just has the ideology of *have it and not need it, than need it and not have it*, it will pull you out better than nothing. Then you wont care about burning a R200 shackle in a pinch. I am not sure if youtubers burn through ropes or what.

I have had melted shackles due to friction on the ring. My winch rope has held up to a certain amount of abrasion with its sleeve, that sleeve wont last with this use but I see no indication of wear on the rope itself yet. No doubt a steel cable will last longer in hard conditions but for me the weight, safety and bush repair argument are worth it. I must still check the heat on the drum to see what its effect on the rope is but people like Matts offroad who use this stuff daily havent reported anything about heat on the ropes being an issue, that I know of?

Try cut Dyneema with a knife. Stuff is silly strong. I wanted to resplice a section of another rope and struggled.

All has its place, and I will continue to test and use the new ideas. But I am not leaving the metal at home just yet.

Take into consideration that dyneema is super static, i.e. no stretch at all, where nylon straps have a small percentage of stretch. No give means a lot more stress on recovery points.
