I have two pipes: a smallish Drinkless Kaywoodie from the 30s and a bent, big-bowl Karl Eric. I now have several tobaccos that I am "sampling". English blends are Frog Morton and Penzance; for burley I have Mello Burley (house brand); for aromatics I just got some Lane 1Q. Plan to get a Virginia, perhaps McClelland 5100 Red Cake. So far I have smoked the English blend and burley in both pipes, though more in the Karl Eric. Just tested the 1Q in the Kaywoodie (only). Just read here not to smoke any one pipe without a day's rest (though will probably try the 1Q in the Kaywoodie tonight). Of these tobaccos (English, burley, Virginia and aromatic like I think 1Q is), which should I segregate to an individual pipe, or are combinations of these tobaccos compatible enough to preclude ghosting (which I know nothing about)? Thanks!
