I use dills , longs , and yellow bole . I also bought a box of 1500 on ebay for $15 . The ebays and yellow bole do leave a little fuzz , so I dont use them on my smaller bore stems . I use ebay bristle cleaners for the pipe bowls , I also use a couple of soft brass brisle gun cleaning brushes on a few of my bowls , mainly the ones that dont require a reaming @ the time . I use a thin shoe string soaked in everclear on the stems that they fit in . Even after a soak in everclear , the shoe string pulls out tons of tar , oils , and gunk . I think the shoe string bit does as good , on some of my stems ,as a retort . After smoking a pipe the last 4 or 5 years im just discovering the wonders of a retort . After a good retort , I need very few pipe cleaners . :puffpipe:
