Hard to beat the ole Fletcher Tru Peep. There is one brand out, the name escapes me at the [email protected], you can change the inner piece to allow for different size holes.

One important thing though, get yourself a good set of strings, then set your D-loop with the viper pliers, this way the peep will rotate to the same place every time once the strings get their initial stretch.

I've been hunting with a setup like this for 5 or 6 years now, and it has not let me down once. Hunting or target.
