A 6 inch replica, 3/4 wide and 1/4 inch thick would work perfect. If you want to do a taper you can but I don't think it would be useful.

That will allow anyone trying them to pick their length or use a whole one with a double hook rig. gives options for 3 two inch one or 2 three inch ones.

Might be a use for larger ones. I am gonna try to get some input from a facebook group I am on.
