I am 57 kilos male, want to buy kite that can help me JUMP ( next stage)
1. 2012 Cabrinha Switchblade
By my calculations, at your weight (and assuming a possible gain of 1 to 3 kilos) up to 60kg, the Switchblade in 8mt or even 10mt will definitely get you kiting in moderate winds up to around 20knots max. And boosting big air time.
But
you have to learn to boost (aka jumping) by learning Load and Pop (plenty of utube videos on how to do it).
