That depends on whether you want something with a bit of "give" or something which will go bang tight and break something expensive. Anybody who has ever seen a 4x4 trying to "take a bit of a run to shift something" on the end of a dead tow rope, or worse a steel cable or chain, will know what I mean. There are plenty of stretched chassis around here to tell the story and all my on shore tow ropes are 24mm nylon
I would certainly say that anybody using nylon should be aware of the properties of it though, as has already been said it can catch the unwary completely by surprise.
I also have a mooring compensator similar to this
which I bought and have never used so I think that might find its way into a tow line as it seems like it might be a good idea - I messed around with it when I got it and it does give a very progressive take up of the strain.
