it was my first board, got it last year.. this board would probably be a great fit for you.. i'm 5'11", 190 pounds and the only reason i'm looking to sell is because i'm becoming more of a park rider and i need something smaller and flexier.. i'm gonna get up pics today
With a size 12 boot I think you'll regret getting a wide board down the line. Just to give you an idea... I'm a size 12 and I ride a 150 (Rome artifact) without any drag or problems. There's not much reason for that extra width unless your really up in the size 13+ range.
With that being said I have a basically new skate banana (built to shred anything, from gnarly ice to fresh pow) size 156 with brand new union force bindings... Size xl.
Bananas are great boards for anyone, you can really take it anywhere on the mtn and have a sick time. Even though it's known to destroy the park (which it does) it can hold up perfectly anywhere else.
I have a Rome Machine midwide that I'll be selling soon. I also have a pair of DC boa size 13 boots. Have you checked your size in each boot? They all run different. Do you need bindings also? I have some Burton Mission bindings also. I can post some pictures and prices if you're interested.
