Eric, you make a valid point regarding keeping things clean to maintain full benefit from your chosen blend. I am one of those folks who after every smoke will dismantle my pipe and hit both stem and airway with pipe cleaners.
Some folks will clean the stem after every smoke yet the bowl only after several smokes. Judging by what I see come out of my airway after a single smoke then it makes perfect sense to clean it after every smoke. Any amount of build up is certain to have an adverse effect on the taste of the baccy.
As for aluminium reducing the flavour, pure codswallop :crazy:
Condorlover, very good :clap:

Jay.
