Take a look at Impact sights. The Cosmic ring is one of the brightest sights out there. They have a movable and imovable sight. I highly recomend them. Spott Hog i found had a lot of screws and things you had to mess with before you got it sighted in(to much hassle for me). Copper Johns makes some really nice sights also, but when i mounted a few on bows, you couldnt get the sight window far enough down to sight the pins in where they should of been. That mostly depends on your riser length and where the bolts mount. The bow i had this problem with was a mathews LX. THe legacy had no problems though.
