Just today I was helping someone out that was new to archery. Their group was all over the place. I installed a kisser button and their group instantly tightned up. She was as happy as can be. I think in time one can get rid of the kisser. I still use one. Do I really need it? Probably not. The way I see it is that when I am up in a tree all bent around trying to get a shot and it is not the ideal form situation, the kisser is just one more thing to help out. As far as loss of speed, come on now, get real guys.
