Hi everyone! I'm 14 years old, 60 kg and just getting into the sport. Im planning on getting the 9m Slingshot REV. Is there a catch 22 to this kite

I havent heard anything bad about it! Do any of you have problems with it?
I'm planning on riding at Woodman's point after a few lessons. Is a 9m kite too much for a beginner of my age? or would that be ok?
I havn't decided yet whether to get a 2nd hand board, a cheap (but new) board or a pretty good new one- probably f-one, is there anything wrong with the build quality of them? I'll get a reasonable harness and then LESSONS!
I'm trying to get the deal where you buy the equipment and then get free lessons, so I want to get it right the first time!!!
I know I've asked alot of questions, but thanks in advance, Michael.
