What would be the recommended "minimum breaking strength" of a snatch strap / kinetic rope (KERR - kinetic energy recovery rope) which would be used to recover a Jimny stuck in snow or mud?

I read that the "MBS" parameter of a kinetic rope should be at least 2-3 times of a stuck vehicle's gross weight.
Anything lower than that factor is not recommended because of the risk of breaking the strap / rope under load.

However, on the other hand, having a too strong snatch strap / kinetic rope is almost as bad has having a too weak one.
If a too strong rope is used for a certain vehicle (for example, a snatch strap with MBS = 16 tons with a small Jmny), it will not stretch because there is not so much weight on it, and it will act almost like a non-elastic tow rope, jerking and damaging the small vehicle.

Therefore, which MBS parameter is ideal on a snatch strap / kinetic rope for Jimnys? I see some rated at approx 5,3T MBS, and other rated at approx 8T MBS.

Would these 5T ones be just enough? Would these 8T ones be too strong?

What are others' experiences?
