Sorry, don't advise starting with a big depowerable kite, I'd go with a cheaper 3-4m kite, if you're level headed and have lower winds, maybe a 4-5m
kite, Radsails, Buster II's or Beamers are all good choices, resale on them isn't bad either, so use them to learn, then buy what you need after.
I'm the same weight and get a lot of use out of my 5m foils.
