I'm sure you're going to have a great hunt. And you get the best of two methods - hounds and bait. As you know, the hounds are likely to chase the bear up a tree. Your open sighted revolver will be a good choice. For my eyes, a red dot wouldn't be a bad thing.
Over bait with shots under 100 yards, use what gives you the most confidence.
Have fun with whatever you decide. We're looking forward to seeing photos!
