i have a 07 gnu riders choice in excellent condition. back then it was considered a very good freeride board (the new gnu are more freestyle boards). i planned to sell it on ebay but could go for a trade with the nideck.
not a bx board though...
let me know if this could interest you
Don't know if this is what you are looking for, but I have a GNU Rider's choice 161.5 that has just 4 days on the snow. It's a freeride board, though (softies).
