I could be wrong (pretty sure Im not) but sidewinder is a woman. Not that I'm saying that matters or anything, and yes she is pretty spot on. I've been working a lot on my form over the last three years and done a lot of video taping/comparing/working with pros/practicing and I can tell that she has done her homework and understands the kinetic chain of a great throw in disc golf.
If for some reason I am incorrect sidewinder I humbly apologize
