Yeah same for me. My first Off axis trick or flip was the misty 5, witch i did when i tried rodeo for the first time. Then i pracced it some and learned misty 5 critical etc, and since it was pretty the same movement for me i just dropped my shoulders, added rotation and reached for the japan.
If ur trying misty id sudgest just throwing a sideflip - only frontwards, so when uve reached air you add rotation. Super easy - Not so steezy trick.
