Thanks guys, good responses! I was lucky to get out a ton last year, and had a blast watching 49 different bears. Here is my perspective on them, having seen watched many of them for extended periods last year:

#1 - Sow about 175 lbs - she had two cubs with her. Judging from the picture, she looks like stocky like a boar, but she is actually pretty short.

#2 - Sow about 150 lbs, although from 500 yards across the valley in the long grass, she looked big enough to spend an hour crossing the creek & stalking her with my bow.

#3 - Decent black boar - about 250 lbs. Only saw him once.

#4 - Big Red - a big fat-a$$ bear, probably a boar. Only saw him once, but couldn't close the gap with the bow.

#5 - Mr. Big - a large cinnamon male. Stalked him 5-6 times to 40 yards, but couldn't close the gap with the bow. He is #1 on my list for some hot lead this year. Haven't seen sign of him yet...
