Mike, as a proud M22 owner I was thrilled a couple years ago when you decided in favor of the M22s and it's something that would remain in my memory forever, but I'm crushed to learn of your change(just kidding).
Okay, if you use them as surrounds the sound characteristics of the M2s, which are very close to the M22s, won't matter as much. If in the future you move them to another room, possibly to serve as mains, then your comment about switching the M22s to the M3s would also apply, and if so it would be better to use M3s as surrounds now.
