I just bought the cosmic by impact and let me tell you what a great sight. Single green pin thats really bright. The only down side was I went to install my 1 piece Fuse quiver and the bracket would not fit. I could have used some spacers but I don't like a quiver that stands far out from the riser. Instead I just put the old Kwikee back on without any probs. Besides I always take the quiver off when I get in the stand anyway. Can't go wrong with Impact, I own a couple of their sights....Very tough and durable.
