Ascents in front and Scenario's in back. I went through two Theater center channels because I was having too many problems with loud crackling noises; so, I had a Cinema in place until I got the Theater fixed. I kept the Cinema in the end since it didn't have any of the problems I was having with the Theater. I used a REL sub for a couple months, and then got the Decent about a month before it went up for sale. Got rid of that since I still preferred the M&K. I love the Ascent's, even if they are a pain to position properly. Finding the right spot to put'em in is a PITA, but once they are properly placed, it's heaven! If you haven't already, definitely follow the placement recommendations in the manual.
