Need Help With DAR

Hi everyone,

I've been playing this game since 2015 with multiple breaks. I have over 2100 hours with old GC as peak rank, 500 or so hours focused on freestyling. All this time I only used free air roll. I can continuously fly and spin with free air roll (even get some flashy resets and musty double taps) but now I want to switch to DAR due to the feeling I get in some positions. I feel like 1 in 10 positions you get to a point where you need rolling and moving at the same time and free air roll can't do that. What is the best routine to learn DAR quickly right now? Especially on wall plays, I feel like there are positions where you can spin faster with DAR but I don't know how to train them specifically. Are there any good training packs or routines? Any help is appreciated.
