They are considerably different from each other.
One weighs 6 pounds the other one weighs 7 pounds.
One has changeable chokes the other one will be fixed. All kinds of things.
Im not saying one is better than the other. All Im saying is that they are different. Im pretty confident you will have a preference for one over the other.
If you cant get your hands on one, do a three day inspection turn around. Of youre willing to spend five grand, you should be willing to spend 75 bucks to be sure which one you like.
