are we talking on dirt? out of a skatepark? cause they're a pretty stock pro trick, as for a skiing trick to compare them to, maybe like switch cork 10s. something like that, either way dirt hurts a lot more to fall on
learn em out of flyouts first. just turn your head and your body will follow, then when u getnem down there fairly easy to get on dirt jumps. well thats what i did.
Its not hard at all, If you can 180 you can 360. Just set your mind to doing it, you'll have it in a few days. The easiest way i learnt was out of a flyout at my local park, Just keep lookin over your shoulder
