Going to Atlanta this weekend to get either a couple bottles of that or the single barrel. I have one of the 2011 LE Single Barrel's in the bunker i have not opened yet, so hopefully trying to gain a little more knowledge on which one is truely the better. The place I am going has at least a case of each for $72 LESmB & $75 LESB.
I would get another bottle, and it got much better with air. And I would also give the nod to SmB LE 2011 over the SB LE 2011.
That said, I actually preferred the SB LE 2009, over the 2009 Mariage, which I know puts me in the minority.
