A couple of good videos to get would be "How to rip", and "How to rip Harder".
It won't help much to watch "Total Insanity" or some other high-octane jump-fest (although it IS fun to watch those!
) They just are not set up as instructional.
Good luck out there, and BE SAFE! Kites are amazingly powerful, treat them with a great deal of respect, and make sure there is PLENTY of room wherever you launch your kite. You will be dragged at some point or another. Be aware of downwind obstacles, people, etc.
