I own a Cascade designs that has the plastic motorcross looking chin guard on it. I also own a Seda that has a huge, burly, heavy as hell, hocky type mounted on the front. Mounting this on the front ruined the helmet, I am a skinny bastard but I can barely hold my head up when I wear it. If I were you I would buy the one that AMP uses here is the link
