I have a Westin Sportsman, and couldn't be happier with it. Its already paid for itself a couple times by absorbing a hit or two that would've caused some expensive damage.
I had a Hunter brush guard on my Adrenalin before I lifted it and I loved it. It didn't curve by the headlights just as the Westin does but it was just as durable. Good buy and easy install. Even has holes for two off-road lights.
I've had the Hunter on my 2002 ST for 3 years now. Pretty durable, and there are indeed holes for off-road lights.
The guard sort of contours to the ST, but it isn't 100% form-fitting. I like the look.
One gripe is that the original hardware (bolts, nuts, washers) that came with the push bar rusted heavily within 3 months or so. Replaced and have no problems.
