Hello to all first I want to say that I'm just getting into this sport. I never rode a surfboard and i cant Rollerblade nor can i skate. I already took few kite-surf. No being on the water yet. The instructor recommended a 10m or 12m Cabrinha switchblade kite. I had seeing really good review about the Slingshot Rally and RPM. I being searching for the best price and here are few kites I found and i Need your advice and recommendation.

2- Cabrinha Switchblade 2011 14M. $800 (Includes bag, pump, and bar. All in excellent condition)

3-14m Slingshot Rally 2011. $900 (Includes bar and lines which
