I have had a blue Amsteel for almost 2.5 years.. it finally broke this past summer, i was pulling out a Big Bad Boy Buggy 4x4 out of a creek.. So i put on my new MasterPull synthetic rope... i have pulled my brothers duramax dually out and his 77 chevy 4x4 out... so yea these ropes are awesome!!
Also they wont have "memory" when your spooling it up or free spooling, so when you give it slack it is like it is... Unlike steel cable and it just goes crazy..
I had the Blue Amsteel on a Warn A2000 for a year and then put it on my Milemarker 3500. it lasted for 1.5 years. Now im workin on a Masterpull on my New Milemarker.
