Speed is key. My other tip is to keep your hands closer together on the boom. This helps to get a bit more lift when you take off. When you take off you bend down in your stance, straighten and then pull it all up again in the air. Squat, stand up, squat! When you jump into the air heading up a little bit helps. You change angle, you bear off to obtain your speed, when you see your ramp if you head up a bit then the wind will get under you gear and help give you that lift.
