I don't usually choreograph an entire song, but I'll first pick out sections that are important to me. Either apparent mood or tempo changes in the music, or different moods that I can fit into the music. Usually that ends up being a smooth section with big arcs, smooth push turns, maybe a side slide; an uptempo section that's more exciting and locked on to obvious beats of the music: consecutive snappy corners (which have that lovely sound), tight cascades, snap stalls, etc.. and somewhere in between things like octagons, tight spins, slower slack line tricks, and the like.
Overchoreographing can go very poorly for me if the wind is light, so once I've picked out the important sections, I'll keep in mind the parts that I absolutely want as planned, a few ways I would like to interpret the other sections, and a handful of moves/criteria that I want to do somewhere in the duration of the song.
I've always been a huge fan of the folks who have full choreography and pull it off the same despite wind and weather though!
