The Natural 3 railer presents itself. By going to the right side rail first I can calibrate the table and zero in on the shot. Makes for a fun closing 7 by Lefty for the game set and match. 

Dual for sure and often the final resting point of the cueball matters more than the object ball. When I can get both right it makes for a more leisurely run out.If you learn that which is difficult to learn, how much easier are the simple things to learn. When I practice the Draw Shot, I most always give myself two targets, one for the Cue Ball & one for the object ball, because it is a dual goal shot.
When I am practicing the Break Shot, I am concentrating on the good hit & leaving the Cue Ball in a certain spot. It too, is a dual goal shot.

Three Ball is OK, I have used a big Phone Book. But, repetition is compromised or taxed with anything, but a BreakRAK. Knowledge, with Repetition is the key to learning physical motion...period.Dual for sure and often the final resting point of the cueball matters more than the object ball.

Percentage is considered in shot selections.
While the contact point between the 2 balls is critical, speed and spin are huge variables. Changing speed or spin can change the required contact point. Rail first practice will show how much speed or spin changes angles.
Looking at object ball last I produced excellent shot making. Looking at the cueball as I strike it gives me the best control of the white.
Three ball is my break practice. Tells me right away if I stuck it well.
Who were you calling?I have used a big Phone Book
Cole Dickson taught me that precision is more critical than power on the Break shot.The Phone Book is great for Hitting Very Hard & not launching the Cue Ball off the table.
Oh I see now! Guess our first phone book would have been a launch pad. Well the whole county had a population of 14,000. Probably about half had a phone.Funny Ha-Ha... Actually I put a wide (1/4") Marks-A-Lot Stripe, in the middle of the spine, going the short way or across the spine.
It's a great target & does provide useful feedback. I lay the Phone Book in the spot are a & point the spine perpendicular, toward the direction of the CB, headed my way. If the Phone Book moves away from me, in the direction of the shot, I assume I hit the spine in the correct direction. If the Phone Book moves backward & rotates slightly, I know I missed hitting it straight on... The Phone Book is great for Hitting Very Hard & not launching the Cue Ball off the table.
