The dragon I did back in '02 and it took me forever, using my original Delta 15". I would cut a few of the scales and get frustrated and set the project aside for a few weeks and then try again. This went on for a few months Last year I did the Grizzly Bear and thought nothing of it (that was after I had cut the Viking Warrior with Scrappile's encouragement). Different saws and experience do make a difference.
