Bull bars ... that is so Canadian
Truthfully though, no point in bothering with a bull bar. A steel bumper with a hoop will suffice.
About the only things you can protect your jeep from, with a bull bar, are White Tails, Black Tails, and Mulies, and Sheep and Goats if you're going that high.
When it comes to Moose or Elk vs. your jeep, at speed they're coming over the hood and into the windshield.
If it's grizz, it's a dead stop, but he won't be dead yet !!! It is exceptionally rare to hit one in the first place, and even rarer that a car sized vehicle would kill one outright, even at speed. Heck, we don't even kill them outright if we hit them with a tractor trailer.
For our flatlander brethren, you remember what they say about seeing mountain lions in BC right? "If you see a mountain lion ... it's too late."
(That's not the same thing as seeing a cougar in Vancouver though ... LOL)
My wife clipped her first deer of the season a week or so ago.. in her under-one-month-old JL (just the tire, no damage). I was planning on putting an ARB Classic on for her before the said incident, but she was balking at the $1100 price tag.
The biggest problem I had searching for a steel bumper for her was finding one that didn't look like something was missing without a winch installed (most recessed-winch-mount bumpers had no covers, just a big gaping hole in the top of the bumper, and most top-winch-mount bumpers had non-removable fairlead loops...).
I ended up ordering a RedRock 4x4 Avenger bumper... which looks suspiciously like a DV8 FS-1 with a slightly more conservative bolt-on hoop instead of the welded-on x-striker on the DV8. I don't have it yet... will report back on its deer-stopping-ability after the next one my wife hits.

I hit a deer with my then-new YJ on a snowy winter's evening. I was driving carefully, below the posted limit, but the event occurred with such speed that any defensive reaction was functionally impossible.
I briefly looked for, but didn't find, the animal after safely pulling over. A fair bit of gore was left behind on the steel bumper and front fender, so I'm confident that wherever the deer went, it didn't last long.
By the time I arrived home (the vehicle could still be safely driven), said gore had frozen solid...and it was still that way when I dropped the vehicle at the dealer for the insurance-funded repair. Three cheers for PA's cold winter climate. Let them deal with it.
I recall being quite grateful for the plain and demonstrably strong stock steel front bumper on the YJ. It absorbed one heck of a thump with no observable damage. The fender took one for the team, but that was the extent of things.
I do wonder how my JL would fare in identical or even similar circumstances. I do also hope that curiosity is never satisfied.
