As long as you have adequate make-up air (MUA) to go along with the 1200 CFM, you should have no issues. I have 1500 CFM with a passive MUA. 1200 should be more than enough. I have a friend who put in a Viking and a 1200 CFM and it smoked. After talking to him, it turns out that he didn't factor in MUA at all. I advised him to open his windows BEFORE grilling, while the grill was warming up. That made it much better, to the point where he could use the grill again.

I have a 48" CC with the 12" grill and I use it all the time, at least weekly. I even use it in the summer instead of my Weber outside. The CC's grill is a much better grill and I prefer cooking on it. If you do get the grill, your only regret might be that you didn't get the 24" grill. I only got the 12" and I wonder about that sometimes.
