Sorry.  I know I've read the sort of comparisons I'm looking for but when I searched for it (heck, I may have been the one who asked the question) I can't find anything. In any event, I know the published specs but wonder what happens in the real world.  To you Ovation owners, what's a typical profile for your longer flights?  Altitude and true airspeed.  Same for Acclaim owners.  And to those Acclaim owners, do you regularly take on the Colorado Rockies and, if so, do you go all the way up
