RE: never owned a bow like this
I like the Tru-Peep for 3D and target shooting and, if you're looking for a peep with the hole sizes that Fletcher makes, there is nothing better for the price. But the G5 is available in a size that has a peep hole you can dang near slide a Fletcher through. I like the wide open view because it's a big help in low light.
Now, I have to point out that the string angle at my ape-armed draw length takes the peep a long way from my eye. I need an oversize peep to get that clear view. For folks with a shorter draw and less string angle, where the peep is closer to their eye, they can get the same view I want with a smaller peep.
