Ok 24mm nylon rope is for most jobs perfect.strops are for winching and standing recovery which equates to not very stuck 99% of the time.
Ropes you can snatch im not on about kinetic thats another debate use the towing vehicles weight to your advantage to unstick stuck vehicle be it 2mph typical use or 20mph (comp recovery use) a rope in good condition rated and attached to a rated recovery point is great.
Strops are perfect for winching and likewise vehicles that's a wee bit
Stuck by means of tensioning I.e taking up all slack in strop and then pulling away. Most things stuck badly this will not work unless towing vehicle has excessive grip.
If you try an snatch or drive off letting a strop go taught to try and use some vehicle weight all you will do is rip off rated tow points shackles and damage the strop itself not o mention cause damage to all occupants backs and necks plus at the Nd of it the vehicle is still usually stuck but now with damaged rec points and hurt driver. The forces involved in a strop suddenly going taught is one of the reasons you would never use a wire rope unless for winching. Forces are hundreds of tonnes instantly on all connecting points.
Ropes because they take the aggression out and the time period it takes to stretch and go taught spreads he loading out and more importantly smooths out the whole thing.
I can go on and on ad have done the reason ropes are almost 10 times the price of strops is because they are more versatile.
I have strops I use them for winching or for a bridal on motors not blessed with rec points a five quid Strop around an old dead disco minus rated rec points is better to attach my rope to than said heap.
