You can get stronger snatch ropes built of appropriately stretchy synthetic fibers at places that sell rigging like wire rope etc.
Just a word of warning if someone who is not Charlie Aarons or another equally smart dude reads this, rigging slings are NOT appropriate for snatch use. They are designed to lift or retain cargo and are carefully designed not to stretch at all.
So rigging webs are not the same as snatch straps. Places that supply rigging probably can supply snatch straps, but make sure to get the right thing.
I guess the moral of the last part of the clip is that perhaps braided/spliced rope is better than stitched ends.
I dunno if I would flatly say that only because a braided rope also requires proper technique to achieve the strength. I guess it all comes down to trust in the person doing the work, be that braiding (if it wasn't you), sewing the sling or whatever. I would also expect that a sewn sling would remain consistent over time since a spliced rope needs to be checked that it does not have internal rupture at the braids and has not loosened or started to slide with use or temperature and moisture changes. I personally feel it's easier to assess the condition of a sewn strap and that's an advantage.
Heck, even a braided rope requires that you trust the material strength of the rope itself, so I suppose you have to decide who you trust, what the true working margin is, etc. Even the ARB straps in the A4WDM test failed close to their rated strength (about 7000 kg) and so under normal use it's unlikely they'd fail any more often than one that meets its ratings. I mean, if you are trusting a 8000 kg strap to work repeatably and consistently at or greater than 6,800kg/~15,000 lbs, then I think you are risking significant failure of any strap due to age, regular manufacturing variance, etc. So if you have a 5,600kg/~12,000 lbs or more truck, I would not feel safe using a 8000 kg strap normally anyway (which is 70% of rated max as working). Not to mention ARB looked into the problem and changed their process, so in that sense I would trust them.
