Alright.. Alright.. I talked to a expierenced ball driller(Bowlers Dream), he cleared it up. It seems that both of you are right and wrong in a way. Let me explain this.

We all know the placing the core about 3 3/8" puts the core unstable, which produces the most flare/hook from a ball. But, putting the pin on(or near) track, makes the core go end over end decreasing when reaction takes place and over all hook.

But, if we place the pin right on the axis, it puts the core in a STABLE position. However, it does not promote skid because the core is turing along the axis, however it does make the ball roll and not skid.

So both of you were right in a way. Pin on axis does not make the ball hook early, but it makes it roll earlier instead of skidding since the way the core is turing, therefore it wont produce much flare, with a controllable backend.

Did I finaly settle the freakin argument? Or do one of you disagree with this?

Brian,

1. Weight is defined as static weights/the ending CG. This can be in combination with the pin and/or the starting CG being on your axis.

A "perfect" axis weight drilling will have both the pin and ending CG on your axis. Starting with a perfect "pin in"(starting CG on the pin) ball. The weight hole will be roughtly 10" from the center of your grip, going past your PAP.

2. Because there is no side weight, maybe just top, this means the ending CG is closer to your track. So, the ball will roll early/earlier.

If there was side weight in conjunction with this drilling, with the right amount of top weight(low top..1/4 oz.), so the ending CG is now on the PAP/pin, the result would be that the ball would go longer down the lane before hooking, and it will hook more on the back end.

If you want to balance balls perfectly, and get maximum reaction, you want the ending CG to work with the core. So, putting the ending CG on the pin will give your maximum reaction with whatever layout/core position. This is because now the pin and static weights are working together and are rotating on the same plane as the core.

Remember, when using asymmetrical cores and core with strong MB or flip blocks, the position you start the weight/core/pin, is not the position it stays all the way down the lane. So, just because you have the ball layed out with the pin closer to your track, doesn't mean it's going to stay closer to your track when the ball gets to the end of the lane.

This is why what the major companies say about how these layouts work, seem to be right. There's things that's not being considered about why you get this reaction. They just tell you the reaction you 're getting, without explaining WHY..!!

Lane conditions also play a major part in your ball reaction to layout pattern. If the lanes are oiled backwards, heads stripped and backends tight, you'll get a totally different ball reation/read than what you're supposed to get, vs a lane condition with the front's oiled heavy and the backends dry.

You'll also get a different reaction/read when the lanes are oiled 10 to 10 long oil.

Going back to having the weight on the side of the ball/closer to your PAP vs having the weihgt closer to your track/ 6 3/4" from your PAP. If the front of the lane was hooking and you stayed behind the ball, the ball with the weight on the side would hook more than the ball with the weight in/closer to your track, thus looking like it hooked earlier. That's because of the side imbalance. One side is heavier than the other.

With the weight closer/in your track, both sides of the ball are equal, so it won't hook through the front. Actually it won't hook at all, because the ball will be rolling end over end, 6:00 - 12:00 all the way down the lane. Because the ball doesn't hook at all, with no hook on the backend, it looks like the ball is going long. It's going long alright, but it's rolling long and rolled out from the start. You need to turn the ball for it to hook, or, the core has to be asyemmetrical so it falls.

Now, things change when you turn the ball/have side rotation. With the weight/pin on your PAP, if you turn the ball/come off the side of the ball, with a 9:00 to 3:00 90 degree side rotation, the core/weight/pin is now facing you, pointing at 12:00 and 6:00 down the lane. Think of it as a spiral thrown football heading down the lane. Now, there is no side imbalance with the core, so, the ball will go longer, delaying the balls/cores precession.

Whereas, with a 90 degree rotation, with the pin/weight closer/in your track, the core is rotating sideways like a windmill thru the front. Because the core is rotating sideways thru the front, the ball will want to hook/roll  earlier/precess earlier, i.e. lose it's side rotation earllier.

So, as you see, different layouts, with different conditions, along with different release's, will do/react differently, combined with core migrations that most bowlers cannot see, explains why it's confusing for you to understand why you're getting the ball reaction you get for a specific layout.

And, this is why you don't comprehend/agree what I'm saying. =:^D
