I'm surprised with the Tatuaje La Casita Criolla comments. I really like the HCB, the smaller size and ring gauge.
I went through my notes to see if I missed anything... these are the sticks that I was wasn't impressed with that were 2011 releases (hopefully I got that right):
Viaje 2011 Summerfest - although not a terrible stick as I did finish it and actually smoked a few of them... I wasn't terribly impressed with them. Specifically the 5 1/4 x 52 Torpedo.
Zino 2011 Embassy Selection - I finished the stick, so it wasn't absolutely terrible. This is an example of me getting really excited about a stick and being completely let-down. The wrapper from the Davidoff 702 intrigued me. Didn't really like it, although I think with more age, this will be a better smoke. I enjoyed the 2010 Embassy Selection a lot more. The 2011 was extremely one dimensional imho.
NHC Surrogates Skull Breaker - There was a lot of hype for this cigar, and I was skeptical before I even smoked one. I kept an open mind, but the thing reminded me of the Viaje Zombie taste profile, which I smoked a few of... sounds weird, but it has this dirty green pepper taste that I don't enjoy. Not complex at all with a flavor profile that I didn't enjoy.
Outlaw Cigar Company's 13 - It's the Nosotros blend. Smoked several of the robusto size. Had some of sweetness but no pepper which the Nosotros had when it was initially release... I never could put my finger on the flavor profile of the 13 or Nosotros, but I know I don't enjoy it. It was released by Outlaw in 2011. Maybe it doesn't count based on the tobacco used.
Torano Single Region Serie Jalapa - I believe this was released in 2011. If not, I think I'm very close on the date. I've smoked like 7 or 8 of these. When they're on, it's a pretty good stick. But it's off 50% of the time. Nice oily wrapper keeps getting me to try it again. When it's on, it has some complexity with sweetness coming in half way through the smoke, but mostly leather flavor throughout.
Again, these were the worst cigars in 2011 for me, imho.
