ok so I am going to use an acinfinity T6 unit for my exhaust fan but was wondering about what ducting I should go with? I see a bunch of brands, is there really any difference with these? I am basically looking at ipower & acinfinity brands.. one thing I was wondering because I was leaning more to the acinfinity was the color.. it's black verses the ipower which is silver., would the silver give me the added benefit of reflection of light as opposed to the black?
