This probably won't help you out much, but if I were you, I would testdrive both, the 310 and 350, since they have them on hand, and form my own opinion.
If they won't let you test drive it and keep the promised boat show price, I would be wary on buying it from them. Like they are trying to make a quick sell. It's a lot of money to take on other people's opinions, especially salesmen who are POSSIBLY trying to get rid of it.
