So far: +15.5% with a 5 for Firestone Walker 16th Anniversary (it was at a bar and before I took notes, but it was the first of that night and it is damn near perfection if you ask me, with all its complexity) That is also my only 5 and thus highest rating. Out of reviews it is Bigfoot with +11.5% for a 4.65. I really need to go out and stock up on them. That was my first one and I really want to try them with age. It really tastes like a top-notch IPA when it is had fresh. -31% with a 2.18 for Sobrehumano Palena'ole by Maui w/ Jolly Pumpkin (drain poured into a beer bread mix) p.s. I realize that the highest rating and lowest rating will most likely coincide with your greatest +/- rDevs.
