Re: Gong kites reviews and tests

Yes, but Unik 12.9m : 745 e Aluula Flite 12m : 2429 $ So you are paying nearly 3x the price to save 28% weight based on your 10m kite data. It is good to have brands making affordable "good enough" products for 95% kiters, and other brands pushing the boundaries of technical innovation and price tags

Thanks it is nice you can try and adjust length this way to find the most comfortable setting Once you have picked one though making a fixed splice is the most convinient. As there is not much bury length the splice would have to be sawn or use brummel locked splice. What do you think about the infe...
