Hi,
I'm not a driller but, I'm a student of such tings and work closely with a friend of mine who is. What you need to consider is that ball setup, i.e., the location of the pin and CG (MB in an asymmetrical ball), is determined by finding your PAP. The placement of the layout depends on that, if you notice every drill sheet locates an "average" spot for the PAP and then mentions distance from there to the location of the pin and CG and suggests a certain general characteristic for how the ball will react. So, if you see a friend's ball with a certain layout that may be identical to yours, it does not necessarily mean that you will have the same reaction from the ball, even if it is the same ball with the same cover prep. You really cannot predict the way a ball would react simply by noting the location of the pin and CG except for very general terms.
Keep in mind also that the cover preparation has a tremendous influence on the ball reaction as well. So, you can tune the reaction of the ball beyond the layout. The trick is to decide what kind of reaction you are looking for and communicate that to the driller. He/she in turn, can recommend a layout and cover prep to help you achieve what you are looking for.
I have an AI and it is a great ball. I have a weaker drilling on the ball with pin under the ring and the CG stacked. For me that is a somewhat weaker drilling . The ball tends to make a mid-lane read (because of the low pin) and a continuous arc to the pocket. I keep mine at 500 abralon with light Rough Buff polish. I handle all of my own surface prep on my balls with a spinner that I have at home.
Generally speaking, the layout you suggest with the Pin high usually will see the ball going longer down the lane. Depending on whether the pin and cg are strong or weak as it relates to your PAP, determines the shape of the ball. If I were to take an educated guess, An AI in out of box condition with the Pin above the fingers on the mid-line and the CG kicked to a stronger position...on a medium condition with clean back-ends I would think the ball would go long and make a sharp change of direction down lane.
Hope this helps.
