ok thanks guys, that's what I will try at the next jump. Thanks for the pictures. unfortunatelly now it's kind of cold in switzerland for jumping. but I hope I can do some exercices this year. I have a windtunnel close to me, but it's expensive. I'm sure I will spend some money in coaching jumps next year.
I think, it will be very helpful to see my body-position on a video. Maybe it doesn't really the same position like the second picture, which I always believe to fly :D
sorry for this english. if you can find mistakes, you can keep it ;-)
