Ive mountain boarded plenty with FB kites, including blades... If its a later model, you can adjust for less lift, and reduce your worry there - just
make sure you go the right way... My first time out with a blade, I went the wrong way and was lofted quite unexpectedly.
Just pick the right kite for the wind and err on the small side to reduce the risk, I guess.
