Replying to Trick tips!

So my rail game has always been pretty good but for this season I'd like to learn some more flips and stuff. I got my 360, 540, 720 down and I can easily do front/backflips. The problem comes when I'm trying to do any off axis trick. I just don't understand them. Only actual off axis trick that I have ever landed was underflip (I tried rodeo 5 lol). So how did you learn your first off axis trick (and what wasit it) and what is the first one I should try.

Amen
