There is a lot of information about ball layouts. From books to articles in the bowling magazines to internet. All seem to want to complicate what is happening.

There are layout systems, such as duel angle and 4x4 with buffers, to name just a couple.

Then there is the layout examples you get when you one buys a bowling ball.

All of these are attempting to one thing: Help a ball driller not to screw up a drill.

All will be correct some of the time, but never all of the time.

Why is this? The why is very simple. All bowlers do not have same release and therefor their ball track, pap and axis of rotation will be different.

Most drill sheets assume a normal pap and around a 45 degree axis shift.

Most ball drilling systems take some of those variations, but not all, of those into account.

The more a bowlers pap and roll differs from the normal, the less accurate these systems are.

Another factor that drill sheets and drill systems cannot really account for is pin placements, specitly in the case of assemtrial bowling balls.

Assemtrial balls can have mass bias placements in realy awkward positions, rendering a ball that can only be drill for a lefthander or visa versa.

How layouts effect ball reactions have been around for years. Before Hammer introducted the hand gernade type weight block weighing several pounds, the most a ball drill had to work with is measured in ounces.

The rules that apply then apply now, only the amount of weight is different. However, with the weight block being several pounds makes the placement of the weight dramaticly effecting ball reaction.

The above gives a person a general idea of why it is mandatory to analyze a persons games BEFORE they get a balled drilled. To do it any other way means the ball driller is either guessing or just doesn’t care enough about the customer to get it right.
