Got my first tag and have a population/predator question

[Gnomepunter]

Well I got my first ever tag this year( Montana Big Game Combo). I have been doing alot of reading about populations of deer and elk in montana.I think I will opt to take a Whitetail rather than a Mule deer due to population declines. And also am interested in doing my part as far as predator hunting goes to help with herd numbers. Just want to do the right thing and help out however I can being a nonresident. I guess my question is would black bears be the most impactful? Due to the hugh calf mortality due to bears? Anyone have any input? Sorry for the longwinded post.
