If anyone were to do this, they should do it according to blend categories. I wouldn't want to sign up for a "tin a month" club and have half the tins in a year be Aros! I think as pipe smokers, many of us have more particular preferences than a lot of cigar smokers (I know I know...cigar smokers-myself included-tend to gravitate towards certain smokes as well), and in my opinion, there is far more variety of flavor in the pipe world. There are people who only smoke Va/VaPers, those who only smoke English blends, etc. So having a "Burley club", a "Virginia Club", and a "Latakia Club" might be a good way to approach it.
