I can tell you this, T.....

If you put 100 hunters in front of you and had them draw their bows.....and you moved everyone's peep sight 1" up (beforehand).......

.........THAT is what they'd notice (once all their other anchor references had been established). If people think their peep sight isn't a point of reference for anchoring.....then what do you trust? Do you just look through the peep......other anchors be damned....and shoot? OR....do you get all of your other anchors set.....and then realize.....no KNOW your peep's been compromised?
