If your group is all good enough to play Eagle Ranch and Copper Point as you indicated you have, for sure play Greywolf at least once while you're there. By far the nicest course in the Invermere area, in my opinion, and very challenging as well. They have group deals for 12 or more at the Panorama Village to boot...
