Ive been working on 4:3 in different ways for a while now. Havent got it down by far, but playing seems so much funnier when really learning new stuff. This part for me is so negleted, so every progress with time feel gives new perpectives on how to use harmony as well.
At the time Im working on just playing 4 notes over 3 beats (mostly arpeggios with four notes or pentatonic "shapes") as well as 8:3. My goal is to be able to play 8 over 3 with only click on "2" (one TWO three, that is) without rushing. I cant play 4:3 yet, but Im closing in. It would be cool to be able to alternate between 8 over 3 and 16s notes tripplets in groups of four. "Time" will tell I guess.
What rhythmic devices are you guys currently working with?
