I used to use fiber optic sights, but was missing a lot of birds over the years, even after patterning the shotgun with them to all kinds of ranges. In 2012 I hit rock bottom when I missed 5 gobblers opening week and 3 more by the end of the season. So last year I just used the default red bead sight. Me and three other people used my gun and went 7 for 7 on gobblers. So I think just using the standard bead will work fine IMO.
