billygold and I have been exchanging feedback on this board so I thought I'd share.
First a little about my boarding.
My first board was a 99' Burton Custom 164 with Burton Custom Bindings matched with some Northwave boots.
Stopped boarding in 02' due to splitting my head open in Mammoth, back side of chair 3 before they had parts of it roped off.
Started back up in 08' and do Corness and Daves run in Mammoth, but nothing more intense so my boarding is about average.
My current set up is Lib Dark C2 158, Drake Mentor bindings with a mid flex rating of 2 (from 1 to 3) and Northwave Decade SL boots with a flex of 7 (from 1 to 10).
I demoed a GNU Billygoat C2 on a powder weekend so not a real good test. It did hover unlike my old setup but felt like a plank.
At first, I regretted buying the Dark out of fears that it was way too advanced and stiff as my old Burton was very loose and that's what I preferred (so I thought).
After riding my Burton for so long, it felt like I was trading in my woman for a new one so I felt odd, sort of guilty.
Having 11.5 boots I also thought the board may be too narrow, but due to the built in riser plates and my bindings, the only way I could have rubbed was at a perfect 90 degree angle.
For our first few runs we hit chair 3 in Mammoth and man, the thing made childs play of ice and turned on a dime, WOW!
So I kept going and dropped in while others were stopped trying to find a line. Damn, this thing killz!
Then after some chair 5 etc, we hit the back side; chair 14 and wow, it just plowz but with finesse.
The next day we hung at chair 9 for a while and man what speed! I still have to get used to it, 2 days is not enough.
This thing seemed to generate its own speed, so long traverses were a non issue.
Powder was what I expected; a hover craft, and moguls were very fun.
I did have issues with tracked out stuff but that's due to putting more trust in my board and needing more snow time, I board 6-8 days a year.
All in all, don't get this board as only I want the unfair advantage
