I use several products from Specialty Archery. Super pee gives you the advantage of changing the size of your peep WITHOUT having to put you bow in a press and re-sevre in another peep, AWESOME! If you shoot a scope, they offer peeps with lens clarifiers in them to make the targets clearer. Also shoot a Super Glow Scope w/3x lens, am pretty happy with this type, but am always looking for any advantage to shooting! Good luck.
