I' ve shot with only a kisser for 20 to 25 years, I really can' t remember when I made the change but it' s been a very long time. I got a target bow recently and thought I' d go the whole nine yards and put in a peep also. I shot with it for about 2 weeks and practiced at all yardages out to 80 yards. I' d say the peep helped in general but past 50 yards I had to start coming off my kisser more and more as I moved back to 60, 70 and 80. At 80 yards I was still accurate but it felt like I had a floating anchor and started second guessing my form and slowly my accuracy started to suffer. I took the peep out and resighted the bow and I' m shooting almost as accurate at 80 as I was with the peep.
Shooting with no peep is not for everyone but for me I' m peepless for all my shooting Olympic archers do pretty good without them
