Need a bit of help. I'm a tweener, medium speed, very accurate, avg 215-220 player. I use a 4x4 layout for heavier oil, and a 3" pin over ring CG in palm layout for medium. I am more effective when I don't have to swing the ball and can be more direct and up the boards for the first 40 feet to the break point.

My struggle has been when the lanes start to break down and the stronger stuff has to get put away. I have a tried going with a pearl for these conditions -- I purchased a new Backyard Bully last year in the same basic label drill -- but the result is not what I expected. I get length, but the backend reaction is very sharp, to the point that I actually have to move deeper when I pull out my pearl stuff! Not what I was looking for.

My question is this: what type of difference in reaction would I get if I moved the pin to an "over the bridge" position in the same type of ball? I did expirement with POB layouts a few years ago, but they were in very weak balls (Threat, the red Blazing Inferno) and the balls were marshmellows. So, in a stronger ball like an absolute or even the exact Backyard bully that I currently own, how much would that pin move --- about 2 inches right -- change the reaction in that ball?

Thanks folks...

OK, folks, your thoughts on this layout:

Ball has a 3" Pin. I'd locate the pin about 2" above the ring. CG location is kicked right about 1.5 to 2" from the center line. In essence, it's about a 4x3 layout. I'd use my old Threat, which has a label 2x5 layout. Thoughts?

P.S. Here's a potential bonus: the old thumbhole may be able to double as a weight hole, given it's location. I may be able to recycle one finger hole as well. That'll save some plug work!

No problem using the old thumbhole as a balance hole, if it turns out to be in the right place. But before you consider reusing a finger hole, check the pitches based on the new centerline. I think you'll find them to be considerably different from what you usually use. -- JohnP

The difference between a "pin" over ring finger to a pin over the "bridge" would only be in your mind. "Tweaks" in the pin position rarely have any effect on the ball reaction. Movements of the pin(3-4") will. The result of "tweaks" (small adjustments) are only noticeable with the ball surface.

-----------------------
Deadbait, I have 2 blueberrys. One is 4" pin drilled pin over ring stacked. The other is 1" pin drilled label. Surface on both balls are the same, & I can hardly tell the difference. I bought the second one(pin in) to drill it up for earlier roll. Is what you are saying the reason I can hardly tell the difference? I thought maybe it was my imagination. Maybe I should have put the pin & cg closer to my pap for earlier roll??

Didn't mean to hijack your post pjr, but similar to what's being discussed.

Update: I plugged my Threat. We placed the CG kicked out 2" right of center line. I placed the 3" pin about 4 1/2 from the PAP (just right of ring an inch above). The X hole (former thumb hole) is about two inches below the PAP and somewhat left.

Well, we had a real bad pair of Friday. Right lane broke down, and the left lane toast right away. I pulled out the Threat for the first time and it worked great. Once I lined up I had a great shot at the hole and carried well except for one 10 pin. Looks like I have a solution...thanks for all the help!!!

John, not yet! I think they are going to pull the string this week.

If you put the pin over the bridge, the ball will go longer, a little less flare, and have anything from a very angular to very mild back end, depending on the mass bias positioning and the particular ball used. In fact the One series of balls recommend this as their #1 drilling layout. The higher the pin(closer to the VAL) the longer the ball will go with the same pin to pap distance. Hope this helps. Joe
