Greetings, Chip, and welcome to our obsession!
For a first-time buggy pilot, I would recommend looking for a kite with plenty of power (you're a pretty big guy), but with friendly and
forgiving flight characteristics, to keep you out of trouble.
The Ozone Little Devil series fills this order, quite nicely. The 4.5 is big, but not scary... power when you need it, but rather slow-turning and
stable in the air, with very little lift while in the overhead, parked position. This means you can fly to the top of the wind window during gusts
and overpowered moments, and the kite will remain stable and not lift you skyward, in most instances. In the deserts of the American Southwest, you
can get in real trouble, real fast, if you're flying too much kite... ask anyone who's been to Ivanpah Dry Lake. As a rule of thumb, fly
the smallest kite that will pull you, until you become more proficient. There are lots of high-performance kites available, when you're more
experienced. While learning, you want something that does not overfly the "edge" of the window and collapse, then fall back into the power
zone and re-inflate under power, yanking you from your seat, if you're lucky, and from the planet, if you're not. Lower aspect ratio kites,
generally, are more forgiving. Higher aspect ratio are faster and quicker turning, but require more skills to manage.
Come to Spring Break Buggy Blast or any of the other buggy events here, and you'll have help, advice, equipment to "try before you
buy", and lots of sympathy when you bollocks it up. <grin>
