I just bought a Grounds Super Mag with a Coco barrel an a polycarb insert. Ive liked the sound of every Grounds call Ive ever heard, but wasnt sure if they were for me(Im pretty particular about the feel of the exhaust end of the call). But I couldnt be more happy and will definitely not hesitate to go to a more high end Grounds call in the near future. My super mag is mellow with a goosey low end and a nice crack on the high end.
