It's also worth saying that tow straps are not to be used as snatch (kinetic) straps .. if you use a tow strap/strop as a snatch strap there's a real chance that the strap won't break, but either the rocvery or recovered vehicle will! There's nothing more designed to find a weak chassis than a snatch recovery using the wrong kit.
In my opinion there's a lot to be said for a decent size 'proper' rope, at least 1" diameter, many fibres, has some give that tow strops don't, still isn't a kinetic, but has some resilience which makes it much, much kinder to either vehicle.
