The only pipe I own that smokes flake tobacco well is a 9mm filtered Big Ben. When I purchased the pipe, I ordered the charcoal filters for it. I intended for it to be an aromatic pipe, but the first time I put a flake in it, I changed my mind. I was just window shopping on the internet today and saw that they make the balsa wood filters for a 9mm pipe as well. I've never smoked a pipe with any wooden filter, but this peaked my interest. Does anyone have any experience with the wooden filters and charcoal filters. I've used the paper rolled style filters before in cobs and they seemed to take more away from the smoke than the charcoal. What can I expect from the wooden style; more specifically, the 9mm wooden filters.
