Dual Angle Layouts – Totals and Ratios

The Total Angle Sum

The Total Angle Sum is exactly what it sounds like – the sum of the two angles that comprise the layout. The greater the total the longer the layout will go. For example, for any given bowler, a ball with a total sum of 100° will push further down lane and cover less boards than the same ball for the same bowler with total sum of 80° on the same oil condition.

So what does this mean? We can change the total sum to suit the conditions we’re bowling on. If we are bowling on shorter, drier conditions, we will tend to want to use higher totals, to allow the ball to get further down lane . For longer, heavier conditions we will tend to want to use lower totals to help get the ball started up sooner on the lane.
