baithuck double back
the only way to get dub backs is to literally just huck and tuck, as long as you commit you will be fine.
dub misty is real easy, just start out with misty 5 and keep rotating to land on your back, after a while just go for the dub and commit, its not a scary trick at all in my opinion.
dub side for me is somewhat similar to dub misty. at least in my head. i throw mine as if its a misty 4 to sideflip (pretty much 90 in dub side)
dub 10 just get good at cork 7's and then start trying to get the set (cork 7 to your back) and the rest was pretty intuitive for me. youtube tutorials will help as well
