question on hooked or unhooked launches

[mrlaroo]

I am a beginner and wanted to know if best kites were good for a beginners kite?
The only reason I ask this is because it recommends launching in hooked in and isn't this a no-no for rookies? I asked them about this question and they mentioned the depower and what not but i wanted to hear if possible what you all thought about it. Also I weigh 125 and I was looking at 9 and 13m kites for my range, would this work or should I go w/ 7 11. I just like the wind range better on the 9 and 13. Well thanks for your time.
