I picked up a couple of tins, after hearing the interview with Brian. As warned they are very dry, but they burn sooooooo Goooood. Rowland Platinum has replaced the dark flake as my end-of-day smoke. It packs a nice nice gut punch that sets my mood for bed. They pack a little loosely in the bowl because of the dryness, but they burn cool and dry.
I recommend this brand. It does take a little adjustment to your way of think that pipe tobacco should be. It will seem dryer than necessary, but trust me, the smoke is good. In my opinion, anyway.
