I think the Star has less dome that the Champion and the Pro has the MOST dome of any of them.
I'm not the only one that thinks that. My buddy Moose is a big gun thrower standing at 6' 8" tall...
He actually was the one who brought it up to me. We went out and played about 6 holes just throwing the champion, star and pro destroyer. the pro destroyer was the most stable.
Plus throw after throw it was consistently stable.
Pro Destroyer.........the stable pig in my bag....
