+1 to what Charles said. If you can fit the vertical center I think it's a win win situation. You'll be cheaper out the door and have a 'better' center channel speaker. I started with a VP150 and ended up switching to an M2 for my center duties. No matter what you decide however, good luck and we'll be interested to hear your impressions once you set them up.

Cheers,
