Not an expert but just got back from a Canada bow bear hunt a couple months ago. They used a variety of baits at each site, never just one thing. Popcorn, honey jars tied to a tree, barrel with honey'd oats, barrel with old scraps/grease/misc stuff, and then a frozen beaver carcass was put in a cage at each hunt(guessing any fresh meat would be the same).
Will 100% agree that having a mix was good, some bears would only come after the oats, others only after the meat even though all of it was sitting right there in front of them. Was pretty obvious they each had their own tastes or food they were in the mood for.
Just make sure to place it all next to a tree or build a little wall/fence out of posts/limbs etc so the bears come around it to get to the baits and give you a guaranteed broad side view.
