New to this, some questions

[bigbluec]

i am new to this sport, I would like to buy my gear before the summer gets here so that I can immediately go for some lessons as soon as it gets warm and start to enjoy myself without wasting nice weather looking for gear.

I am 5'9 and weight between 190 and 205 pounds ( depending on how much I work out ... want to be 205 by the time summer starts)

What is the best size kite to buy ........ from what I have read it seems a 12m kite would be the best ???

How big of a board do i need for surf kiting in a lake ? ( Great lakes of Canada) waves are not very big.

What is the difference between a Wakeboard and a kiteboard ? does it matter which one I use ?

Thanks .....
