I say we brainstorm a bunch of layouts, mock them up, run a survey, and have people rank the layouts in order of preference. Rank whatever layouts you would buy (so if you only would buy one of them, you'd only rank one; if you like them all to varying degrees, you rank all of them, etc.)
Then, using the CSV you can just do simple math on the table. 1st rank gets 7 points, 2nd rank gets 6, etc. (something like that). Whatever gets the most points wins.
Or maybe we can come to a consensus in the thread. We agreed on Dolch pretty quickly on the last one.
