Sounds like you want to get into landboarding.
You should go to more of a landboarding knowlegable site.
check out www.foilzone.com
several very good and knowlegable land boarders there.
Also check out the flexifoil forums.
For landboarding you want to get the right type of gear.
I would say the most important thing is you want a kite that is very good for long float and soft landings. High aspect ratio foils are good for this.... they really resemble paragliders.
You also want a kite that does not have too much downwind pull so that it's easier to use a land board.
If you think that you might get on the water in the future you can get foils that work on land and water.
