Hyawatha, I just went through this myself. I have used a Cobra Devastator sight with a square clear pin guard for the past 4 seasons. Last year I tried the No Peep. I didn' t really care for it so I took it off and went back to a Peep sight. I have been looking at the round pin guard sights, and reading in mags. and on the forums about the benefits of it for centering in your peep. So I ordered a new Vital Bow Gear Profix sight last week. It is a single pin sight with the round pin guard with the orange on the inside of the guard. Boy did I make a smart chice. It has really made a difference in my shooting. It really helps to center the pin in the peep and hold a more consistent aim. I am glad that I did it. It lines up perfect in my Super Hunter peep. It is a wise decision to do it in my opinion. Also, I can' t believe how bright this sight is. It has a foot of fiber optic wrapped in a spool around the guard. I held it beside my Cobra and it is many times brighter. I can' t wait to hunt with it.
