Can you please run some flat strap along your verticals. That is just dangerous and will cut anything you hit in 1/2. If you are looking to see how to do a proper job check out the ARB ones. They are designed to rigorous safety standards.
Anything hit with that bumper, with a strong enough impact to cut a deer in half will cause fatal blunt force trauma anyway. If I were to god forbid hit a pedestrian going at a fast enough speed to cut them in half will be just as fatal with the stock bumper and grille/headlight/hood. The bumper was specifically designed to prevent a deer hit from flinging it up over the hood to go through the windshield by quartering and locking the hit into the three barred zones. This was specifically designed and built by me right after my wife hit a deer in Montana with our 97 suburban, and seeing how super lucky she and our 3 year old daughter was to have the front half of the deer bounce up over the hood and come through the windshield between their seats and miss them.
If I wanted to go the european rule way, where if they had their way every car would have a marshmallow front end..... then that would be fine, but interestingly, they are now finding the new mandated designs are increasing the incidence of flinging the people up over the hood and into the windscreen, so now you have two fatalities, rather than just the one. Kind of like the same brand of govt mandating what is good for us without thinking the resulting changes through... how do you like them wonderful carb compliant gas cans???? they actually guarantee that you now end up spilling 50 times more fuel and "fumes" then you ever did with the old style cans.... but try to bring that up at govt meetings and you are labeled a neanderthal environmental hater.
Note, other than the purposely designed flat plate verticals, my design follows most of the Australian recommendations for Rural environment vehicles. (flush with top of hood line, soft rounded sides and edges on the horizontal surfaces, angles back on the top side, mounts Over existing bumper, with a 4" crumple zone extra built in to the new bumper.
