There's a kiting forum around here somewhere where you'll get more answers for this kind of question.
www.seabreeze.com.au/forums/forum.asp?forum_id=10 and there's also gear reviews that will sum up the finer points.
Most of what you'll get will be biased on the surface, with a little truth in it.
My biased opinion is; the Rebel is great as a "safe" learners kite. The 2010 has a good reputation, as did all it's previous models. It's a 'vanilla' kite if you need it to be.
What little i know about liquid force is old news and not-nice/biased. so i don't need to share that.
Spend more time focussing on skills and judgement and less on worrying about gear.
(but you'll be fine with a rebel

)
and if you're just trollin' well done!
