Dual-role dancers: when a festival registration makes you choose a single role, how do you decide?

Do you flip a coin? Register as a leader on the assumption that follower spots will fill up first? Try to guess which role you dance slightly more often?

My usual answer when asked about my preferred role is “a good night is when I get to dance both roles, but my favorite thing is to change roles mid-song.”

I caught the last hour of last night’s milonga. I danced every tanda while I was there, 3 as a follower and 3 as a leader. Saturday night, I showed up for the last 30 minutes; I followed 2 people and then led 2 people.

I’ve never been to an event that didn’t have a “both” option since I’ve only attended queer festivals and marathons, but I’ve seen registration forms for non-queer events that lacked that choice, and I wonder how others handle that.
