I've got class in a few weeks and am hoping some of you can share some insights pertaining to picking an aircraft. I've got a fairly high SSN, so my fingers are crossed that I might be able to pick from whatever is offered. I know that it's been all NYC for a while and probably will continue to be, but my goal is to get to DTW as quickly as I can, as I live 30 minutes from the airport.

So, which plane should I shoot for?

What would get me to DTW the quickest? Off of reserve the quickest?

Any guesses how long it might take to be awarded DTW? Have a line?

These questions mainly pertain to 737 vs. A320. There's a possibility that the 7ER would be offered, but I'm guessing I'd be dead last on the list for a very long time. The 717 is probably also a possibility, but I'd rather not continue to do regional type flying.
Thanks in advance for the advice!
