Last couple of weekends I have been smoking my Armellini 9mm filter pipe, getting used to the dryer smoke...loss of flavor true but what I've noticed is about half way down the bowl that flavor starts comimg back. And I'm not convinced it's a loss of flavor but more of a subtle flavor. I also like the non-gurgle aspect of the filter pipe. I'm using good quality charcoal filters (Stanwell, Peterson) no generics. Anyway yesterday I switched over to a non-filter pipe for my afternoon smoke but found the transition a little tough, gone was that dryer cooler smoke and back was minor tongue bite with stronger (bitter?) flavor. I used a pipe cleaner to take care of the gurgle (which really doesn't bother me as I love the mechanics of pipe smoking...the loading, charring, lighting, tamping). But I found myself wanting to go load my filter pipe. The non-filter pipes are certainly more traditional and there is a better variety available, however there are plenty of high quality filter pipes out there as well, Savinelli, Peterson, Vauen to name a few. So folks the question is can you switch back & forth from filter to non filter with a smooth transition of enjoyment? Or must one commit to one side or the other?
