Yes its well worth the money once you start scaring yourself silly from little jumps - then realise most kites will jump quite well with
CommitmentGet yourself a vest and a helmet - kayak style padding inside
As this will give you the Superman effect

and will prevent being winded or head injuries until youve got it down - goin large has a way of teaching you Respect

After people get Slammed a few times it dwindles there self confidence and tend not to jump any higher...

Good luck and have fun
