Maddie or Madison? Help please!?

I can't decide between Maddie and Madison. I know I can always call Madison Maddie, but I want her middle name to be Lee. To me, Maddie Lee sounds better than Madison Lee. Lee is sticking. Maddie doesn't age very well in my opinion, though. I also like Madelyn, but Madelyn Lee doesn't sound good with all of the l's. The last lame is Muller. Suggestions maybe?
