Bears are my absolute favorite! I look forward to moving back to Canada so that I can hunt bears again. I haven't hunted bears in Manitoba but I have next door in both Ontario and Saskatchewan. My best advice is to look for a bear with a small nose. The biggest bear I ever shot was one that had what appeared to be a small nose. When I got to him after shooting him, it turned out that his nose was a normal size, it is just that the rest of his head was bigger than normal!
Good luck, hold out for the one that feels right.
Cheers,
