I have always used a nock set for a rear site,mainly to check my anchor point. I've tried the peeps,kisser's, and everything else,and I always go back to the nock set for a rear site. Its worked for me nearly 30 yrs. and for several years my average yardage was 61 yds per 1 shot kills. Also I shoot fingers,don't know how it would work with releases. Digger
