Afghan Cheese, the high is great, but the smell of the bud seals the deal, its a real! pungent smell, it took 8 baggies and a smelly proof one off edit to stop it stinking out my friends room, so yeah out of those 3 I would go with WW for the high, Blueberry for the taste and smell, and trainwreck..well i've never had trainwreck or blueberry, but I have heard much about it, If you really wanna get fucked though buy some WW
