That depends on your swing speed and the type of ball flight you're looking to create. The lower the loft of a driver, the harder it is to hit. Faster swingers might want to opt for a lower lofted driver as the face is flatter and they can really rip through the ball to launch it into the air. Slower swing speeds may want something a little more lofted to help them project the ball into the air off the club face.
