I'd say stay with a bigger one for hunting bows. 1/4" is a good size. You get so much more light through them, and low light situations are common. It sucks to have a good shot present itself and not be able to see through your peep. I had that happen several times back in the 80's when the pin guards were square and you centered each individual pin, so you needed a relatively small peep to maintain any resemblence of accuracy.
