The stuff above was only in my prized possession for a very short while because I decided to sell it to further fund more TAD! Although I do slightly regret letting the cutter-top slip thru my fingers, it ended up paying for itself five-fold. The BS Flake I actually did try and wasn't too taken with, but it was a decent smoke.
Now my prized possession is probably this MOB #111 Flake, it was the first aged tobacco I tried and it was what convinced me that aged tobaccos actually are very good and not just a myth. I think it's from 2008, but I'm not sure.
Otherwise, my prized possessions are not really rare, just hard-to-get, like Stonehaven, St. Bruno, Germain's Brown Flake and Warrior Plug.
