I would greatly appreciate some help in finding a new suitable board....I'm 6ft tall (1.83 cm) 185 pounds (84kg), shoe size 11,5 US. I'm looking for a mid-wide all-mountain board. I used to ride a 2010 Burton Custom X. I found it to be a bit too unforgiving and taking under consideration that I only hit the mountain about 20 times a season, I'd rather have a board that I can ride in a more relaxed fashion, and go anywhere from powder to park. I was looking at the 2012 models and the following caught my attention:
Burton Custom Flying V
Burton Mr.Nice Guy
Holy giant text!, check the font size before you post next time. Anyway, NS Legacy would be a great choice, has always gotten good reviews as an all-mountain freestyle board on here and other sites and NS has a history of building quality boards. As far as Lib Tech, check out the the T. Rice Pro, basically a mid-wide and quality is on par with NS and both are better than Burton IMO.
Rode the SL, great board for cruising if that's what you mean in a relaxed fashion. If I was heavier I'd check out the Blacklist. Arbor boards have top notch fit and finish, the westmark I had was a thing of beaut.
Don't know anything about Lib and Gnu so others can chime in there. I will say when I was still looking that I was eyeing the TRS
