I don' t understand how you guys are losing sight of your target, or getting vision blocked at all. I just went and drew my bow and I am not close to losing any vision. I use mine for two reasons. It takes away any chance of losing an arrow off my rest, and I am getting better flight than ever. If I am losing fps it is minimal and I don' t care and the wear on the tips of my feathers has not gotten any worse after the first 25 shots or so and is a non issue.
