RE: Peep, kisser or both?
Peep sight points of reference or 'anchors'.
1. String touches tip of nose.
2. Hand against the side of your jaw.
3.Eye looking through peep.
4. Sight aperture centered in peep.
Kisser button points of reference or 'anchors'.
1. String touches tip of nose.
2. Hand against the side of your jaw.
3. Kisser in corner of mouth.
More points of reference with the peep so I would go with it or both of them. I use a peep only. Its like others have said in earlier responses, if you anchor your draw hand consistently you don't need the kisser. On the other hand if you hunt only and aren't in to 3-D and you don't take long shots the kisser by itself would probably be adequate. Maybe try it both ways and go with what works best for you. Good luck.
