I have the tough country bumper - I bought one of the first ones sold. It's been through alot and I haven't had any issues with it getting damaged. We actually had a stuck accelerator and hit a 6" pine about 6" from the right side at about 15mph or so and it didn't get damaged at all. I haven't bashed the skid below the bumper much besides pushing over small trees, but it's lived up to being tough!
That said, I love the way the warn winch mount looks - clean lines, minimalist, etc., winch still mounts up high.
Wanted to add that I originally had a warn pro-vantage 4500 on the Tough Country, and have almost stalled the winch with no ill effects or flexing that I noticed. Recently replaced the 4500 (due to almost stalling) with an Axon 55-S. Wouldn't have replaced the 4500, but needed a winch for a RZR 570, and thought the 4500 would be better suited to the lighter vehicle. Have not made any pulls with the 55 yet.
