I use my long life bags for everything. I have one in each of my CT22's and they have never given me any problems. They're sucking up everything from drywall dust to wood shavings and they seem to be as effective today as they were the first day that I bought them, these things are being emptied atleast 3 times a week, so they are being used. After one particularly dusty day, I used my central shop vac to clean the inside of the one bag; after it was as clean as the day I bought it, so now I do that to clean them, every few months. The benefit to them is that I'm keeping all the spent bags out of the landfills and I dont have to cart around a cyclone (which is now sitting unused, somewhere in the attic. I also dont find them particularly dusty to clean them out... just put the plug into the hose port, take off the plastic closure strip, place the top of the bag at the very bottom of the garbage bin, and let the dust/ debris slide out, no unnecessary shaking, and they is virtually no dust!!
