Which Martin Logan Center Should I Get?

I am building my theater room and I need to buy a center speaker, which can be debatably the most important one, and wanted to know which one to buy. I already have Martin Logan Odysseys for the front and ML Scripts for the back (it's going to take some power to get them running...) and I am deciding between multiple martin Logan's for the center. I am looking at ML Stage x, Cinema, and motif, and want to know which one would be the best fit for my 3d projector room. Thanks!
Don't just think 'center channel' speakers. Use the same speaker that matches the right/left you are using. I know that does not work in many cases but should be a consideration.
