I haven’t done my submission yet, but wanted to share something of my experience. I was having trouble picking the kit I wanted to use (I was going for one). My “potentials” list (based on what I could see myself using as much as preference) contained about half the submissions. I therefore wanted a way to help me narrow that down, so I came up with a plan.
I randomly selected one that wasn’t in my candidate set (by random number) and went through rounds of elimination among my candidates removing the ones that worked least well against my randomly chosen one. After round 5 I had 3 remaining and couldn’t pick based on match to the random one. I chose to removed the one that was most like what I’d normally use, and the one that sounded least like me. The result is a duo that will hopefully work without being too familiar/comfortable.
