Thanks for all your help! We've decided to go with a 42" Kobe Hood - CH0042SQB-1. It has 2 internal blowers with max CFM's of 1200 - which is perfect for my 6 burner wolf range. I ended up going with the larger size because the Kobe and the Broan 36" hood only had max 1 internal blower and 600 cfms. External or inline blowers were not an option for our project. The salesman recommended the 42" Kobe and I was surprised to find that when I looked at Houzz for "larger hoods" I actually liked the look of the oversized hood over the range more. Since I have upper cabinets on both sides of my range - the larger hood will create a larger cook space opening - and less risk of the smoke going up under my cabinets. Also - I like that the Kobe is made from 18 gauge steel (with no seams) which is closer to the higher quality 16 gauge Wolf hood and much better than the 22 gauge Kobe. Price point is also very good - I'm getting it (without the duct cover) for $1240 (as part of a much larger package).
