I like English blends in the Country Gentleman and VaPers in the Diplomat, but that may be an idiosyncrasy. The Great Dane is a nice shape, too.
On the recommendation of this board, I purchased two of the Walker Briar Works forever stems and alternate them among my cobs. Don't get me wrong: MMs are fine with the standard stems, but the Walker stems are a fantastic upgrade to them for very little coin.
