Personally I would never go back to a steel cable. I have been using synthetic for many years now, on my quads and now the T4 and I've never come across a situation where I thought steel cable would be worth the hassle. I use mine for utility work out on the farm, for plowing snow, and for trail recoveries. Cable is heavy, makes you bleed, has dangerous recoil, and it birdcages and gets all kinked up and is generally a pain to work with, lol. I've never noticed synthetic rope deteriorate due to age, but I do tend to replace them every 3 or 4 years or so if they have had a lot of use. But that is just because they are relatively inexpensive to buy and get a fresh one spooled on (and they are WAY easier to spool up than cable too). Can they fail in the field? Sure, but no more often than a steel cable, and if they do you tie or splice and are back in action in 5 minutes instead of calling for help with a busted cable. The only situation I can think of where a steel cable may be better suited would be for snow plowing because that can wear a synthetic rope out, but I use a 2" wide cargo strap spooled over my rope for plowing so I've never had that issue.
