Nope, havent tried the new warns. Got a Warn 2.5 on the Grizzly 660, and the cable snapped while plowing the other day.
I have a Venom "Hardcore series" 2000# winch on my wolverine. Its cheap, but its been alright so far. The switch stopped working one day, and we took it apart and found metal shavings in there. Cleaned it out, and its been flawless for the past couple months.
