Appreciated! I think that's the catch about most off-road bumpers...you never really know how it's going to handle unless you accounted for a specific purpose (like big 'ol deer guards on semi trucks...a very singular purpose). Tube, plate, and formed steel construction have very different characteristics, too. Plate is surely the best impact wise because of its hard angles and fully-welded/bent seams, but as such will also weigh more. You can reduce weight with thinner steel, but then other reinforcements are needed. ARB uses 3mm steel (just under 1/8"), but still comes in close to 90-100 lbs for the R50 bumper, and it's still quite big. Dustin's bumper (the other current thread) turned out great; it's a beast of a bumper. I'd estimate the weight of my setup is probably half that, though.
I would have liked to have gone plate, but when I started doing the front bumper, it boiled down to what was feasible in the garage; I didn't have a way to cut plate or make long cuts (to be honest, I really didn't even know how plasma cutters worked until this year!), nor a way to bend round tube. I had a chopsaw and protractor (and I hate dealing with angles). I think it's turned out well for what it is, and it's definitely been a learning experience.
