Midgetracer ... I agree with the others here ... and I've had steel cable on my winches on my truck & my Grizz. I do a lot of winching & use it every winter with my snowplow .... and I will never go back to steel cable winch line.
The synthetic rope is much easier & safer to use ... IMO .... here's some reasons why:
1) Won't get a kink in it when overlapped when winching.
2) If the rope does happen to break while winching, the rope doesn't store energy & therefore won't come fly'in back to "Take Yer Head Off" as Battlegun wrote ... it will just fall to the ground. (I've had steel cable come back & go thru windshields ... not fun.)
3) The synthetic rope doesn't get burrs on it, that rip yer hands when spooling out or in ....
4) Lighter in weight ...
5) Easier to drag out to a winching point, move around to get into position, etc.
The only downside I can think of is, you have to make sure the rope doesn't go across any sharp edges, or might become cut in anyway while winching ... you have to remember ... it's rope ... treat it accordingly.
I've had my winch rope on my Grizz for over a year now. Ran it out the other day to clean it & rewind it after my last winching exercise ... have two seasons use with it with my snowplow too ... and the rope STILL looks like new ... one snowplow season with my steel cable & that stuff was ruined !
And like Smoothbassman wrote ... all the new winches are coming with it.
