Hi there , this is my first post in your site .
I've been doing some search for the subject and seems to be you guys can help..

I sail boats & windsurf since long , tried kite surfing once or twice..
I'm frequenting a nice sand dunes desert region the last years , good winds , suitable..
I would like to surf up & down dunes , jump .

I've been thinking & checking on boards & wheeled boards..
I've been thinking between kite or windsurf sail better option..

First idea was board like snowboard : metal bottom , fin shaped edges no wheels..
in consideration rough surfing terrain and manoeuvring on soft sand..
Then sail idea goes to windsurf sails rather than kite but I wonder what would happen on dune leeward side..

This is subject , any advice ?
