When we go out we generally have a couple of pull straps. The bigger rigs have the full size with loops only. They are a much stronger end and won't rip the ends off like the tow straps with the hooks do.
I however just carry a 10,000 with hooks simply because it is much easier to use then the others. It takes only a moment to throw on a rig, and most of the time you only need a quick tug.
I believe the rated strength of a tow rope is the amount of weight you can pull on a regular basis, where the break rating is at what point you will probably break your strap. Remember, pulling a 2,000 lb vehicle out of a hole will sometimes take over 6,000 lbs of pull strength. Not to mention the initial shock from when the strap first hits.
If you do a lot of "Connect up, hit throttle, bounce in the air, back up, try again" then you will probably want a rope with a bit of stretch so it can absorb the shock.
