I am buying a 30" induction cooktop and is in need of a hood. I do lots of Wok cooking, currently I have a Imperial SL (750 cmf) and it is not working for me. The house is always smoky. From the cooktop to the roof is about 7'.

Should I get a Prestige (1200 or 1600 cmf) or Best by Broan BE12 (1200 cmf) External Blower? or Kitchen Aid

Noise and performance is a key issue for me.

Thanks.
