If you're willing to let go of 2 I'd take the 36 and the 38 that has the cutouts. I work near west wash and regent so running down to the greenway cross area during the day sometime would be no problem. With this kind of chainring stash, what are the odds that you have a 13t cog I could take off your hands too? Otherwise, the dimension cogs are cheap and easy to find.
This week is already pretty packed for me but if there's a time that would be good for you next week I can block time on my calendar.
