Mr fishy, I beleive a peep will help you shoot more accurately. be sure and get at least a 3/16 aperture. I always used a 1/4" . the bigger hole will help you in low light conditions.
but, if your like me and your eyes have gotten bad, then I' d suggest drop the peep, put on a kisser button and get yourself a xhair sight. I' m shootin better since I dropped my peep, simply because I can see my target better. the xhair sight will help you get the right aiming point. I aline my vertical xhair a little behind the shoulder, and the horizontal just below center of chest.
