Jon Olsson is an amazing skier, and him coming out with the Kang flip was a good thing, now that he's coming out with the Hexo and Dj flips, it just makes him that much better for pushing the limit. If you can do a kang, good for you, if you can't then don't hate, they are getting kinda old for sure, but they are still one of the most difficult tricks. I can't do one, don't think i will, but when you see one in person, its fuckin impressive
