Finished cleaning up a Savinelli Sherwood Rock Briar 9004, and have given it five smokes so far, but this is my first pipe with a twin bore stem. The pipe's draft is wide open, which I like, but the dual bore in the mouth piece is amazing! With each sip I have smoke traveling into my cheek and the center of my mouth simultaneously instead of just a single flow. I may now hunt down this feature in future purchases. I am glad Tobacco Treasures gave me the opportunity to discover this feature. Thanks Faye!
