Brunswick provides general purpose drilling layouts which will apply to every bowler differently based on multiple variables. These variables include the bowler's ball speed, rev rate, axis rotation & tilt, and lane conditions. All or most of these variables should be known so that the best possible layout can be chosen for each ball. We recommend that you contact your local Pro Shop Professional for more detailed layouts and how to apply them to your game for each ball in your arsenal.
