Along with my other Missouri Meerschaum cobs, I have 3 that are the Washington model. http://www.corncobpipe.com/product.php?productid=16154 All three smoke fabulous and the flavor I get from my tobaccos are superb. Two of them are older (about 1 year) and the newest is about a month old but well broken in. No matter what baccy I put through them, they all smoke and taste great. Along with the newest Washington, I purchased 2 new Diplomats. The Diplomats are well broken in now, with about 15 smokes each. I've noticed something that I can't explain. All 3 of the Washingtons always produce a superior taste, no matter what my choice of baccy is. But I've noticed that the same tobacco smoke through either of the Diplomats just don't taste as good. Ever. The Diplomat has a thicker wall, and slightly larger bowl than the Washington, and a hardwood bottom, but that's all that I'm aware of. I just can't explain why neither of the two Diplomat models match the flavor I get with the Washington. Has anyone else noticed this? My local tobacconist only carries the Washington model in his shop. I'm wondering if he knows something.
