I like to roll with a 15 year, as opposed to the conventional 30. My wife and I are also fortunate to have a pretty good credit score (785) so that helped out as well. The 15 year loan shaves quite a bit of interest off if you can afford the extra monthly payments. My former boss refinanced last fall to a 10 year and got a 3.2% I believe. That makes sense. Still a great rate! Good for you!
