1st shot: (say i'm cutting to the left, and i'm using a center ball hit) i aim the one of the three lines I have broken my ferrule into the contact point (yes, you heard me, i AIM at the CONTACT point, thats what i like about the way i aim) on the object ball.
2nd shot: (again, say i'm cutting to the left, and i'm using center ball) i do the same thing as above.
3rd shot: i just find the contact point on the first ball, then according to the angle of the shot, i use whichever of the three lines in my ferrule that is appropriate for the shot.
again, i'm using a way of aiming that allows me to aim at the contact point (bascially the line to the center of the pocket) ( this is not one of hal's systems that i know of, but it seems to resemble them because you don't worry about cheating the pocket, and you can use it for MOST any shot, though you can use hal's systems for ALL shots)
alot of times, i also use CENTER TO EDGE on these shots.........but i won't go into trying to explain this.
