Congrats. I think the MSU program sounded really good. It was a tough decision for me to decide to opt out of the DO match. I would have ranked the DO programs here in MI very highly if that didn't mean losing my chance to consider some of the MD programs I liked too.
You're also lucky that you don't have to worry about Resolution 42. Even though several different sources have indicated it shouldn't be an issue, the uncertainty that I'll have until I know for sure it's approved is giving me heartburn. 🙂
