People's reasoning can be their own, but for me it would be for STOL performance, visibility, and history.
It's always experience dependent, how much multi time do you have? Also after you have a 100 hours in type insurance usually drops off a cliff, so that's usually a "first year" only price that goes down subsequently.
couple reasons, at least why I would be more interested in a 337why choose one over a P-Baron or 340 and vice versa
