Thank you all for the explanations. I really am a beginner and do not have experiences to understand and differentiate openings in other models and brands of canopy. when I talk about turning spins are usually 90 or 180 degrees, sometimes the canopy opens and keeps spinning, but not always. I think this is what really happens in the opening stileto, lack of practice. I will pay attention to the packing of the canopy. I like it and want contiuar flying the stileto. Thanks guys, you guys helped me a lot.
