The Send, Snap, Sheet Technique
Send, Snap, Sheet is a good way describe the technique. (say it while snapping it out on your fingers) The tempo gets quicker as the wind speed increases, or on smaller kites.
The Send- 99% of people send it from 10:00 or lower to 2:00, and pendulum under the kite. If you assplant or drop like a rock, that's probably what you're doing. Send the kite from 10:45-11:00 and limit the back travel to 1:00 MAX.
The Snap- happens right as you're about to leave the water (after sending it). I say snap because you want to snap your hips away and upwind and get a clean release. Imagine trying to dunk a basketball springing from your back foot.
The Sheet- start your jump with bar sheeted at least halfway out, and after sending and snapping away from the kite, you begin to rise vertically if you did everything right. This is when you sheet in.
Hand Positioning- if you're hands aren't in close in higher winds, you're gonna pay the price. (sending it too far, or landing too hot) Learn to fly the kite with your wrists and really focus on getting the Send, Snap, Sheet technique down. In lower winds, you can move your hands out a little bit, 1-2 inches at a time.
Remember, you're not jumping a ramp, you're riding an elevator.
There's a few more tips on there as well.
Enjoy Your Flight!
