And if the in line fan's motor is in side the pipe and not external, the condensate with raise holy hell with the motor. I used a squirrel cage fan on mine with an external motor. I do however agree with maple flats that it may create too much flow if you have a pre-heater in the hood. It also depends on which style hood you are useing. My hoods fit onto the pans so that the fan does not drawn cold air in them( i am sure that there is some air leaking in because they are not sealed air tight around the pans) where as if your hoods are just canipes hanging over your pans. that would suck alot of cold air.
