Good idea about the circle to circle .I have also went to 019 optics from029.I also add a sight extension and that makes them smaller also but you pick up every little movement in your shooting form.I take the extension off for hunting.THE peep i use 1/8 hunter true peep.For the deer hunter might go with the ones with the rubber tube thangy.

It pulls the peep straight.And if your sights have a sqaure sight houseing you may change to sights that have a round houseing or sight gaurde.This will make you more accurate and consistante
