The string should come across the corner of the mouth regardless if there is a kisser or not,the string is much smaller so there is less room for error without a kisser.


If you don't use a peep or hindsight,then I would say they are a must but with either of these,they are in the way.


There is a reason you RARELY see a kisser on a target shooters bow.


OH WELL,to each their own.
