I prefer a single pin movable sight.I use a Cobra easy slide ..but there are many other good ones out there. I have 3 settings marked on my sight(20,30, and 40 yards). With this type of sight you get a better sight picture because of only 1 pin...plus there is no chance of using the wrong pin..a mistake that countless hunters make every year.It only takes a split second to switch yardage(about the same amount of time it takes to determine which pin to use on multi-pin sights!)The extra moving parts on this sight has never been a problem for me..and I have hunted in rain, snow, and just about any nasty condition you can think of.
