Whilst I understand the terminology "Label drilling" it is about as relevant as "pin at 1-30" or "give me max finger and side weight".
There is also no fair or real way to directly compare any 2 different layouts. Each layout is unique, and has it's own benefits and downfalls.
There is also no point anymore, in getting 6 balls and drilling them all the same. This is because it is the layout combined with the balls RG and Differential values that gives us the amount of flare for the ball, and how quickly it migrates through its axis.
The most important thing first, is to find the bowlers Positive Axis Point or PAP. This will tell you how to place the pin to control the angle of the core. Once you have found the PAP, you can use the following guide.
Pin on PAP - This uses the balls lowest RG value and also the most stable position the ball can be placed in. This is also sometimes called a 0 pin to pap, and places the core at a 0degree angle
Pin is within 3 3/8ths away from the pap - The closer the pin is to the pap, the less overall flare the ball will produce. As you move away from 0, and get closer to 3 3/8ths, you increase the flare potential. A ball with a 2inch pin to PAP will generally roll fairly early, and quite smooth, if all other variables are similar.
3 3/8ths is exactly 1/8th a bowling ball diameter, and as such places the core in exactly a 45degree angle, its most unstable position possible. This is the only possible position away from the PAP that can be called Leverage. Anything else anywhere else cannot and should not be called Leverage.
As you move the pin furthur away from the PAP, the flare starts to reduce again. The difference between a 2 inch pin to PAP and a 5 inch pin to PAP, is the 5 inch position uses a higher core RG value, allowing the ball to conserve its rolling energy until furthur down the lane. The maximum one should place the pin away from the PAP is 6 3/4 (which is a 90 degree core to PAP angle) for risk of reverse flaring.
There are other variables to take into consideration to decide a layout (balance holes, pin height, High RG axis placement, bowlers revrate, speed, axis rotation) But all other variables are completely useless until you know the bowlers PAP.
All the best.
