Couple o' bits...
@Ram Wagon - yep, Elk are mega-common around here (I'm about 15 miles off from the elk reserve in Clatsop County). Fortunately, they tend to keep to the other side of the (Nehalem) river in my neighborhood (I have yet to see one on my side of the river in the years since I moved out here; now the other side? they hang out, migrate, etc.) And while I have a greater chance of hitting a loose horse than an elk on this bit of OR-47, I think Id want the crumple zones to do their thing with that much flesh.

As for the arguments pro or con? Okay...
Out here, avoidance is a very narrow thing - swerving (or even breathing on the steering wheel) is a guarantee of smacking into a cliff, falling off of one, eating someone else's grille, flying off into the river, putting a tree trunk into your glovebox... when it comes to swerving, let's just say that we don't do that. Nope - currently, my big defense strategy is two-fold: make sure I keep the brakes in kick-ass condition, and the common sense to take it a bit slow around blind corners, especially at dawn and twilight.
Good news - I can almost always slow down to nothing or practically nothing when something is in the road... 98% of the time it works. That other 2% of the time, I'm going mega-slow by the time contact is made. So, I'm not too awful worried about building a rolling battleship, as much as I am in putting something in place that's a bit stronger than the ABS plastic used to make up the grille. Something that can give an errant deer (or horse, or goat, or...) a shove, without having to go out and buy Yet Another Grille.
HTH a little
