RE: peep sight
Want my opinion? I think the crosshairs in the peep is not such a good idea--just short of saying stupid. Your eye will automatically center in a peep with just a hole, assuming it is set in the right location. All those crosshairs accomplish is cluttering up the sight picture.
I don't quite understand your anology that the C-peep was blurry, but will explain it this way. Your eye cannot focus on two things at different distances from your eye. It's physically impossible. If you are focusing your attention on the target even your pins will be blurry. The peep should be blurry also. In fact, you should not be looking at the peep. It's just a hole that "is there".
That being said, my personal choices for hunting peeps is a Fletcher Magnum Hunter (1/4") or even the new G5 in 1/4" or 5/16" hole. Have good strings and no tube aligner is needed.
