I'm in a small bind. I will be getting a NanoQ from BBQ Guru for Xmas any one have it on their Smokin Pro with SFB? My main question is the fan, should I get the 10 cfm or 25 cfm? One website says you need the 10, BBQ Guru says the 25. Of course the 10 cfm is alot cheaper, so what ya think, will the 10 make due?
