Yes... I prefer to keep my layouts fairly consistent from ball to ball with minor tweaks.

I still have a couple pieces that are outside my benchmark range, but they don't come into play as ofter or for as long.

Ive drilled and thrown a lot of equipment. I have probably 3-4 layouts I use consistently with the difference usually being the pin distance. I have found using the same layout on a few different bowling balls makes it easier to transition from one ball to the next as needed.

The key word here is "few".
You cannot expect to use the same drilling on every ball because each ball's designed-in ball reaction, RG, Differential and, if applicable, MB/PSA strength can vary widely. A Dual Angle is specific to the bowler's release AS WELL AS the ball's characteristics AND the oil amount & pattern.

Chart of exact same layout on a bowling ball just moving the pin from 3,4,5,6 and the charted ball thrown on the lane.

Layout is 30 x ## x 75

Second charts is the same ball with two different layouts

Typically the results were surprising. The P1 or just above that on the bowlers VAL reduced the balls flare and overall hook.

P3 and P4 increased the core dynamics and the flare of the ball. Interesting enough when graphed on the lanes the ball with no weight hole vs a P3 or P4 had more over all hook including on the backends. The bowling ball with the p3 or p4 hole hooked a little more earlier on the lanes and flattened out much more on the backends.


The only example I have is on a rico layout graph I saved for future reference. The first line is with no x-hole the second is with the x-hole. The x-hole increased the bowling balls rg, diff and int diff. The x-hole was 1'x3.5" in size.

I do this pretty much on all my stuff.  I like to keep the pins above my ring which puts it around 5 inches from my axis and then depending on the shot shape I want, I tweak the distance of where the cg/MB are in relation to my center line.  If I want ALOT of angle on the back, I will put the pin above the bridge which puts it around 5.5 inches and the cg under the ring finger, no weight hole and adjust the surface.  If I want something to help read the lane better and go for more of a hard arc, then I keep the pin above the ring finger and adjust how far out I shift the cg/MB, typically between 35 and 45 degrees with a weight hole down. 

I do not do anything with a weight holes in P1 or P2.  I always go P3 or P4; especially if the differential is low.  However, I do for specific purposes have a ball with the pin at 2 inches, cg in the grip and no weight hole for when I encounter a short pattern and/or flying backends where I need control.  For the most part, everything I have in pin above the ring, cg out at 35-45 degrees and a weight hole down.  Then, last but not lease, adjust the surface to fine tune the overall ball roll.  I like to keep it simple.

2 or 3 drillings, I can understand.
1 drilling for all balls will only work if you're very lucky,

Or if you just bowl one league in one center.

Or if you're just not very good--like me.      Too much variation in shot making can render layout differences virtually meaningless.

We should all be very "not very good" like you. Heck, I'd be thrilled to be half as not very good as you!!!

Nice to hear from you again, Ray!
