I never checkered my grips until I got a shop bow from Wes Wallace that had checkering. He highly recommended it, although I never had chosen to have him do it on any of the other bows I ordered from him, basically because of what has been said about grips and accuracy above. However, I like it, and have him do this on all of my bows now. He checkers the palm swell, but not the throat area, which seems ideal to me. It really pays off when using cotton gloves, which tend to make the grip slip around in the hand. I don't have a problem with the checkering biting into my hand at all.
