Thanks! I only plan on making the $350 payment since I am not past final payment yet. So the MR loss won't be too bad. But I didn't realize that those are lost if you cancel the card!
Sadly, when I called about retention offers last week they told me there was nothing. Surprised since I did use the card quite a bit. If they had thrown some MRs my way I probably would have kept it, because of the $100 travel credit.
