tjameson, have you tried the BJ Long tapered extra fluffy pipe cleaners and their bristled ones? I have been using those for a long time and find they are really good. The only problem with them is on a couple of my older pipes, the stem hole is small and I have to use the Dill's on them.
This reminds me of another pet peeve, a stem that is so small it will not take a extra fluffy cleaner. I have an older( 1970's ) Caminetto, and my 2 Willmers that won't take a fluffy, and it is annoying.
Another is a pipe that won't pass a pipe cleaner, that to me is an abomination. I have a Mastro De Paja and a Meer that won't pass a cleaner. I bought both of those very early on in my pipe buying and didn't realize it was a big deal to me. The Mastro smokes good but I don't reach for it very much because of that. My son smokes it more than I do.
