Nice profile pic!
Have you looked into any of the board with length reduction "technology" in them? I prefer a much longer board. At 175 I find a 158 to be the bottom end of what I like, but I'm charging groomers, and then riding deeper powder and trees.
The Burton Nug comes to mind. The one designed for a 175 lb rider is a 150. There are other similar boards out there.
The idea with those boards is, the flex is designed for a larger rider than the length would suggest.
Unless you like riding noodles?!?
