Funny was just talking to someone who had been talking to someone (a known user on this forum) who has been playing around with the slingshot turbine and the reports are good. Only a couple of hours ago actually. Gonna look into it.
But reading in between reviews that delta worries me as the wind picks up. As you know to really get some of the more adventurous tricks some ample power coupled with a smaller board seems to work best. This kite looks more like a freeride kite to me, not sure the low aspect and delta with afford the hangtime you require and the delta will become a handful in those winds you really want to lay it all on the line and chuck the crazy stuff in. Easy kite to use as most delta Cs but I'm not convinced as yet it's an airstyle type kite.
