Since you have a knack for large stiff mens boards, I would agree on trying the Black Snowboard of Death...it may be too stiff though. Another good hybrid is the Salomon Sabotage.
If its gonna be strictly a groomer board, a full camber might be fun for days of just carving....
Try the Rome Anthem, Burton Custom X, or Salomon Burner. They are all pretty aggressive full camber boards, but would be real fun to snap around on groomers.
Hopefully you can demo a few decent boards!!
