Are there any opinions on a good airfoil for 2,400 pounds going 200 MPH?

Lynn,
 
What are you wanting out of the airplane. Max cruise efficiency? Gentle stall, high alpha operations, STOL? need more info. What is your wing loading and aspect ratio? What type of flaps do you plan to use if any? What is your projected landing speed?
 
I like the 65 series NACA airfoils. There are more modern sections but they tend to be more temperamental or have ugly Cm numbers.
