start out with a 4 line fixed bridle kite with handles or bar. Get a 3m size and learn from there.
The 3m will be good up to 18-20mph for your weight at a guess.
Ozone flow is a good model to start out on.
After a while you will want to upgrade into Depower. but for now learn the ropes on a fixed bridle kite.
Also go to www.kitecrowd.com
. That UK Based forum has alot more landkiters on it and you will get more advice than this one which is mainly kitesurfers and snow kiters.
