I think the reason the kisser button is ripping up your lip is the short ata on the bow. I use to shoot 40-41 ata bows with a kisser and never had a problem. I went to a 337 this year and had a problem until the kisser was set the exact same distance from the nock as my longer ata bow.. I think the shorther ata bows have such an extreme angle that the kisser will rip up your lip. My kisser still irritates my lip but not to the extent it did before it was set the exact amount of distance above my nock.
