I found when I was learning them that it was easier to do a late or shifty 360. If you know how to do a 180, simply do that half way through your air time, still looking at your landing. Then rotate your head the other way and do your other 180 as you spot your landing and prepare for impact.
This is more applicable when doing it on a bigger jump, but it can also work on small ones too, you just have to do it all faster, haha.
If you simply huck, you might end up corking it unintentionally which will either make you bail or land mad sketchy. Practice dude, and you'll be stompin em in no time!
