I would personally go w/ the Flag. Just a feeling. They are both supposed to be good boards, but I think the Flag is a little more all-mountain focused. The Rome website would describe it as "fun for most everything". The Gnu website describes the 11up as "wide freestyle". Both are good boards, but with different niches. Plus, the Flag looks sweeeet .
I found some great snowboard deals. Could someone tell me, however, if the HEAD Giant 157 snowboard is good? The Rossignol Legion 156? The Nirto Revolt Bindings? I am not a pro, and i dont think getting a burton will make any difference..? Ideas?
