Bravo for your October experiment. Brilliant! Like you, I have fallen in love with Tats. Definitely my favorite NC overall. I have very limited experience with the Monsters though. I bought a Pudgy box last year along with a box Of Jekylls. Bought a box of Hydes this year. Other than that I have never had any of the others. And with the insane cost of old ones I most likely never will. My main concern with purchasing old Monsters is that they will be well past their prime. Which you just basically confirmed for me. Doesn't seem like they age well. I still have half the box of Jekylls and havn't had one in awhile. I wonder if they have gone flat as well. This brings up the issue I also have of holding on to stuff instead of smoking it when it is fresh.
