For the information of potential Falcon smokers, and a question for experienced Falcon owners, about the Falcon moisture rings. Moisture rings fit at the base of the bowl in the so-called hydrodome. They are its built-in moisture trap. Since I didn't order any moisture rings, the staff at Iwan Ries enclosed two made out of pipe cleaner short sections. After three or four bowls of enjoyable smoking, I realized I needed to put in the second ring, and make some others from pipe cleaners. The draw gets a little restricted and the flavor isn't as crisp. My next move will be to try smoking my Falcon without the moisture ring, to see how that works for me, maybe just wiping the hydrodome out after each smoke. This is a pleasing little pipe, and I plan to keep it in rotation, with or without the ring. How have other Falcon owners found the pipe smoked without a ring? I'm glad I availed myself of the IR sale and bought this inexpensive pipe for even less, for a smoke as good as most.
