Yeah, I know. With my 300g soon to be set up I am really rethinking my poly stock. I went all upper jaw with a weeksii, delhezi, palmas plamas, Buettikoferi, and teugelsi. When I see the 'big boys' in the lower jaw group I want to add them but just dont want to mix.... I guess I could just keep adding more upper jaw types. lol, your a bad influence!
