Kiting is lots of fun! All the best with the learning progression.
I started with an 11m as a first kite then 8m for higher wind days and now a 14m for lower ones.
My 11m gets 65% of the use with 8m 25% and the 14m 10%.
I'm around 75kg, as you get better and more confident you will tend to lean toward being more over powered than under powered but starting out my preference was always to be underpowered.
Hope that helps :)
As for brands everyone has an opinion.. I'd try for something newer than 2012 to get you started.
I would have thought as you progress you would go to using less kite? For instance all newbies start on 12's (being their only kite) which they invariably fly at 12 o'clock in 30knots. When I was out at Rosie that last 40-degree day there were plenty of 12's out while I was fully lit on a 7m!!
Requires more skill to fly a smaller kite in lighter winds and smaller kite is more fun. Being overpowered on a big kite is not fun.
I'd say a 12m kite in 30knots while learning is perhaps - dangerous?

Each to his own I guess but I'd rather be towards the over rather than underpowered end of the spectrum now..
While learning I always tried to be on the smallest kite out.. worst that can happen on a small kite is I go down wind and have to walk back..
A guy asked me to launch him the other day on a 12m with most out on 8's (no idea how to de-power his own kite) I suggested he might like to wait till the wind drops and I landed his kite for him...! Talk about an accident waiting to happen!
