I am sorry to put my bobs in here, but ....
why are beginners not encouraged to try foil kites!?
Seriously, they ....
* don't need to be that big,
* have great wind range,
* deal with gusts a lot better than inflatable kites; and,
* have the best depower and release systems out there.
* Oh and no bladder issues ever! To me that is worse than dealing with tangles - if any!
Yeah sure, they are a mind-field for impatient people when rolling, packing, unwinding lines, hot-launching, etc, but once you get the hang of it, most foil kiters never look back.
I use both LEI and foils, but I only have at the moment a land open-cell foil so I cannot really kite over water, but even that can be done.
Anyway my point is if a beginner is taught in a foil kite, they are going to learn kite flying and the principles of kite surfing a lot quicker. They will also learn self-launching and landing from the word go - an essential kite surfing skill in my view.
PLUS
Foils are almost the essential ingredient if you want to progress to advanced directional or foil-boarding, which is taking off and becoming extremely popular recently.
Because they are 3K sleeping bag with strings attached

Watermate, Darren at ASWA suggested another good option worth demoing for us heavyweights is the 18m Juice. Maybe Puetz has demo'd one?
At 15knots you can bet there'd be a lot of 80kg blokes on 13-17's so i wouldn't even bother with anything less than a 17.
