I live in the country, and see tons of deer and branches that are sometimes unavoidable. I really want to try and fit my HS with a bull or roo bar to try and mitigate the damage. Any thoughts on whether or not a corolla bar would fit on the hs? No chance I can find one already made for the HS

 

All I can see is your license plate. I doubt the Corolla bar will fit. Try to post better damage photos and a photo of the Corolla bar you are thinking about.
Odds are unlikely you will have the same sort of impact twice! Although it is deer accident season here in VA....

 

Those bull bars, especially the ones for cars, only serve cosmetic purposes. You could literally spend hundreds or even thousands of dollars on one that is simply thin steel tubing. In many accidents, they actually do MORE damage to the car they are on because the bolt directly to the frame or subframe, and transmit crash energy, rather than absorbing it. The exception to this are full bumper replacements for trucks and SUV's, and Police-style bars that are meant more for low speed, low energy pushing than for high speed, high energy impacts.
