Hey man just wondering what Panasonic Whisper model you got that you werent happy with. Ive been using my FV-08VKS2 80cfm in a micro setup for almost 5 years and I had to blow into a big carbon filter to help silence her down to stealth nearly silent levels. Ive been thinking about upgrading to the 150cfm model so want to know which one you had an issue with.
