No peep sights?

I went to my local archery shop last night who are the most straight forward guys i know! They told me do not bother and put the biggest peep sight on they have and it made a HUGE difference even shooting the action screen last night, man did that get the blood flowing drawing back on big gucks in the black tunnel! They said they carried them for 2 years and people loved them but they also had MANY people have trouble with them coming loose or moving a slight bit ect. He said it is just to many moving parts unlike a peep sight so for now I am going to try this bigger peep and see how it works. Don’t be suprised to see one on my back up bow this fall though to test it out.
