Side Rail Stack Drop

Freeze two object balls to the long rail. The center of the first object ball is aligned with point of the side pocket. You can play around with this distance depending on how the balls drop for you. Tap them in good and they'll support the third ball on top of them. Make sure to keep an eye out on the spacing between the bottom two balls as this will affect where the third ball drops. I like the cue ball a half diamond from the side pocket.

I use the diamond sight where the stacked balls are as my aim point. I use a lot of draw with a half tip of inside (left) english. Hit it pretty firm so the balls will drop when you hit the first rail. Hopefully you can get the top ball to drop near the same spot every time. From there, you can adjust your aim or hit to compensate if you're going long or short. Also, if there are a lot of divots on your table already, the balls could drop differently depending on which corner you stack them by. You might be surprised, so try setting it up in different positions.
