the shop set my bow up while i watched but my arrow is not in line with the holes mentioned. is it safe to say those holes are dead center of the bow? i was using a ultra knock( i call it a horseshoe) but switched to a string loop because the guy at the shop said the ultr knock could be a cause for not so tite groups which is the reason i brought it in. i never had real tight groups probably average.i wanted to learn myself so thats why im asking everybody i can on proper set up of the rest and knocking point. the other thing i need to know is how to set the knock. i was always told to set the knocking point so my arrows are 1/8 to 1/4 inch high but this pro shop guy swears it should be level with a release. also im looking for an opinion on a peep site. im using a rifle type site called erradicator. do you think if i add a large peep to my string to it making it a 3 point sighting system accuracy will improve? sounds like im gonna have to try everything just out of curiousity
