This summer I am trying to learn double flips on the trampoline to bring to snow and help me gain confidence and air awareness for all tricks. Currently, I can do every single flip. I have been working on my double Cork and occasionally land it, but mostly land on my stomach/knees or my side (I'd love some advice on some film I have if anyone knows how to and is willing to critique my form). Personally, I can only train a certain trick so much before I get the farthest I'm going to get for the day. If I then continue to work on the trick I start developming bad habits. I want to work towards another flip after Ive worked on my cork for as long as possible. Which other doubles should I work on?
