I'm not quite understand the dual angle layout. Like in the video.
Ball #1 , Control Drilling , 70 x 2 1/4 x 50
The 2 1/4" Pin to PAP distance control the flare. And the large angle sum makes the ball transit slow. Which the ball will not hook too much and sudden change direction ?
Ball #2 , Strong Mid Lane , 15 x 4 3/4 x 30
4 3/4" , large flare pin distance, but what's the purpose using this distant ?
Small angle sum , Small drilling angle in relation to the VAL angle, create more mid-lane ?
Why the balance located at P2 ?
