Getting a object ball to follow thru?

Draw works but balls need to be pretty close together and the ball in pocket a hanger.
How much separation? Ever tried to stick a ball in place of another? Near impossible. Following it in is more a function of an accurate hit than anything else. The draw might be a concession to that since you can cut the primary ball and hit it pretty firmly too.
Draw only helps when the two balls are close together, otherwise the object ball just needs natural roll.
Follow is nothing more then a rolling ball. An interesting fact is that a cue ball can not over spin in place when top spin is applied due to the downward force of the ball into the table and friction. Hitting a cue ball above the center of percussion does not create more top spin… the only way to generate more spin is to hit the ball harder.
An object ball behaves like a cue ball hit on the equator, so there will be a linear transition between slip to rolling based on distance and friction of the cloth. Distance is your friend here because you want the transition to be completely into the rolling phase.
If you can jump the cue ball with draw and hit the object ball above 2/5 radius you theoretically could cause the object ball to start off immediately in the rolling phase, but ball to ball friction is much less than tip to ball friction, and conservation of momentum will cause the object ball to jump, causing the ball to remain in the slipping phase until it lands again, so it gets more complicated of where the optimal height for a micro jump would be.

Darren Appleton covers it pretty good also. The British apparently call it the "skill shot".
Easier to roll it.
i think that's a term specific for english 8b, where darren started from. maybe it's harder in e8b since they're playing with a pingpong ball as cue ball
Darn failed to cover balls embedded or off to one side - some of which are impossible.

Isn't this effect we are seeing more of a basic, global truth though, for all shots? Doesn't draw on the cue ball impart opposite action on the object ball, meaning follow, which is why Darren's method actually works? In fact, doesn't this 'opposite spin' effect happen for ALL types of english, imparting an opposite spin on the object ball when struck?

We get some transfer. Maybe 10-15% on many shots but there are many small factors in play. In R&D it was impractical to compute so it was off to the test lab! In pool it is always off to the test lab, we call it feel.

When the 2 balls are close,
a) you need backspin on the CB at the instant of contact,
but just as important
b) you need the axis of CB rotation to be inline with the direction the original OB needs to travel
2nd ball must be hit dead full. That's by far the most important thing.
It's a skill shot until when you need it.
