Warning, serious LP whore!!!!!!!
LPs = awesome fresh
LPs = awesome aged
Freshies are stronger with a bit more body, aged (18-months+) have more refined flavors, and more of them! If you like your #9s sweet, get ahold of some aged ones ... amazing. If you like the syrupiness and baking spices of the T52, those things come out even more with age. So it's a trade off, a preference thing, and I love both. Because of this, I have close to 100 of each at various levels of age. (Same goes for the Dirty Rat--mellows a bit with age, but the flavors are more "alive" too)
As far as size, my preference is Flying Pig, then Toro. But every size is great and I keep a few of each on hand when possible (note to self, out of #9 DCs, get some before spring!).
