Well, let me throw in my vote for the M60s.
They will allow you to cross over at 60Hz (or maybe even 40Hz) rather than the 80Hz (or sometimes higher) for the M22s. Although your sub will fill the gap either way, getting some bass from your Mains means that for a good part of the bass frequency range, you'll have three sources instead of just the one with the sub. Though the sub will already play louder than you'll ever want in your room, with three transducers you'll have a more even bass in the room.
If you ever get into some music listening down the road, many find the M60s by themselves better than a speaker/sub setup. Finally, you'll have better resale value and more flexibility down the road....
