When I learned about the air-pocket method, or whatever other people may call it, it really opened up how to smoke cooler. My cobs never gurgled, but my first Peterson did. Once I started the air-pocket in the Peterson, it really started to smoke well. Once I wasnt worried about running a cleaner through it I had a chance to slow down and relax into the smoke. Subsequently I also learned to dry my tobacco more that I thought I should which aided in tastier smokes. Now I do it depending on the pipe, or blend.
