I live in a state with light wind summers and with springs and falls that have strong to high winds. I'd guess Vermont is like that. Eventually you will want a longboard for the light wind summers. When you and your wife reach that stage you can buy an older relatively inexpensive longboard. AND you will still want to keep whatever you start with as a wide beginning board for it's stability and planing in the strong and high winds of spring and fall. The easiest way to increase your time on the water is by extending your season into the somewhat colder weather of spring and fall.
My advice, start with a board like the Rio for two reasons: it will make your start as successful as possible and it will extend your season for years or decades to come.
