I only have one pipe at the moment. Been smoking it since about the end of June. I clean it with pipe cleaners and paper towels before every smoke. I also have only two "house blend" tobacco's I smoke . My question is about the last three bowls I have smoked in it start off good as usual but by about half way finished it starts tasting pretty bad. Has anyone else experienced this? If so what do I need to do? Any help is welcome. Thanks
