Ok I get it more now.tegirinenashi wrote: ↑Tue Apr 25, 2017 6:27 pmTo justify multiple product lines kite vendors list some flying attributes -- how well does kite perform in certain areas. Needless to say, this is entirely subjective, and you just can't compare kites from different companies based on these "info". For Airrush lithium they claim "forward speed"=8. For cabrinha it most likely matches to "boosting" (which slider is maxed). Curiously, Airrush has boosting attribute for union, but not for lithium(!) -- that should tell you something too.
To reiterate my earlier message, the performance of kite is determined by its shape. If two kites are similar in shape they would fly similarly. (This assertion has obvious exceptions, like making one kite twice as heavy, or messing up its bridle). Airrush union is much closer in shape to switchblade, which would translate into similar flying characteristics. Airrush lithium has noticeably "fatter" profile, which improves some characteristics, but diminishes the others.
However I am still confused on what I should choose. To be honest since I am a beginner and haven't got much experience it is probably impossible to choose due to lack of knowledge and comparison with other kites previously used. However, although I might feel slightly intimidated by fast turning kites I might go with Lithium since I am think if I learn with a slower turning kite I will later still weird going to a faster turning one.
