My preference in MM cobs are the great Dane Egg, Diplomat and Patriot. According to the factory section of their website these have a lacquer finish as opposed to varnish on the cheaper pipe. I have notice that after the bowl warms up, the finish feels somewhat softer than when it is cold. Could this lead to finish wearing/rubbing off? If so, is that even an issue? Since I belong to that group who thinks cobs smoke best when broken in and caked like a briar, I wold like to keep these going as long as possible.
