Blake,
Good to see another western Missouri hunter on here!
I've been looking at boats for that same reason (late season hunting on the MO river, Truman, etc). I'm going to pose a question on your post since I think I know the answer, but want to see if some of the guys with more experience will verify this. Moving upstream against the Missouri can be a challenge. It really hauls. The traditional BBSB hull is a displacement hull, which won't ever win any speed contest, no matter what horsepower you put on it. However, it'll get you home through some really nasty weather every time (sort of like reeling in a bobber, it pushes a huge pile of water as it moves). I think more of a planing hull would be a better choice for the MO River. With big lakes like Truman in the mix, one of the hybrids is probably the direction I'll go (black brant III is what I'm currently thinking I'll build).
To those of you with experience on rivers like this, would you agree/disagree with this?
Scott
