DO NOT use a plastic kisser button on a Exile that still has the TRG. I decided to try a kisser button and guess what happened on the first shot Pieces of the kisser flying everywhere.........mostly in my face! I still have welts on my cheek. Upon examining the setup, it appears the string can come far enough forward at the shot for a kisser to hit the TRG. I think I may just tie a not for a reference or use a cushion nock which is soft and quite a bit smaller. Glad it didn't hit me in the eye!
