Just a couple comments: You say you don't ride in the park yet you want a smaller board. That is a little contradictory - usually a shorter board is better for park-pipe/freestyle riding while you would err on the longe side of your appropriate range for freeride/big mt. riding. With that said, at 185 I'm guessing you comfortably fall in the 160+ range for most boards so if your current board feels too big you could go down a little. Check recommended weight ranges for particular board once you narrow it down.
With size 12 feet, you'll want at least a mid-wide, if not a wide board. If you can do a mid wide without toe dragging, it'll be a little more responsive than a full wide.
I'm sure you'll get lots of recommendations on brands, but there are many boards that fit your profile. Avoid park/pipe and total powder big mt and look for all mountain (freestyle/freeride) boards from each manufacturer. I haven't ridden Rome, but i've ridden and like these brands (with all mt. wide options in parentheses): Ride (Machete, Antic?), Lib-Tech(Skunk Ape), Rossi (OneMagtek?) and NS( Legacy, Heritage X?).
