Asymmetric Layouts • Maximum Hook & Arc – Good for most House Shots • Mid-Lane Hook & Back -End – A favorite for fresh PBA and Sport Conditions • Length & Back -End – A favorite for broken down PBA and Sport Conditions • Length – Good for most broken down House Shots • Full Roller Options "These layouts are very general and will apply to every bowler differently based on multiple variables. These include the bowlers 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.”
