I wouldn't buy any unless it was constantly in stock. Can't miss what you've never had. If i had some penzance, i'd smoke penzance and only penzance for a couple months noting down what i like about it and then start to try to create that. Not create a penzance match, but a blend that contains everything i like about penzance. I couldn't care less about the mystique or rarity of a blend. Only flavour and smoking quality matters to me.
