RE: How many don't use a kisser anymore?
instead of bringing the kisser to the corner of the mouth...which moves all around anyway....why not try putting it on the line of your eye tooth. Open lips just slightly and set the kisser on the front of your eye tooth or incisor. It will never move resulting in a much better anchor anyway. It is also out further to the front and you can catch it better with the sharper string angle. I also slide my kisser down closer to the nock on shorter ATA bows. You can use it, just slip one on the string and slide it up and down until you find a spot that fits. You can use it on the tip of your nose even. I gave up my peep for hunting YEARS ago. Using a kisser, jaw, and nose to a knot served onto the string and looking around the string w/my right eye resulted in a much better sight picture and none of the worries associated with the peep. I got used to this and can shoot just as good scores without it as I did with it.
Good Luck. Holler at me(PM) if you have trouble.
