Asymmetric Zone drillings
« on: November 17, 2005, 11:38:14 PM »
Hi there,

I have a general question concerning the stretched Danger Zone type core used in the Zone Classic etc. and drillings. In the drilling instructions included, there is no drilling recommendation which puts the pin directly below or above the finger holes. All drillings suggest a pin placement closer to the PAP, probably 4 1/2" or less.

Does anybody know if there is a technical reason for this, or is it just marketing to have the ball move a lot and make it look spectacular?

The background is a friends' Strike Zone with the pin below ring and the PSA marker next to the thumb. The ball does not move as it has been expected to do - in box condition, polished, currently with Rough Buff finish, and either on sufficient oil nor on a short 35' or so THS pattern. Even different players with speeds of 13 mph were not able to make it move more than some boards... strange!? We are puzzeld and think about plugging and re-drilling it.
Could this occur because the drilling is simply too weak for the core and that a strong drilling simply HAS to be apllied to the Zone balls?

Any experience or comments are welcome. Thank you in advance.

I don't work for Brunswick so this just pure speculation. It might be due to warranty issues.

The box that the ball is packaged in has a warning about drilling the holes to close to the locator pin and how it will void the waranty. That is all I can think of as far as the drilling instructions.

Without seeing the layout/surface/lane condition it wouldn't be fair for me to try to guess what the problem with your friends ball.

Mind telling us where you're getting these drilling instructions?  All of the drill sheets that I have for the asym Zones have two drillings with the pin at 5 3/4" from PAP;  the diagrams show the pin above the bridge for both.

I bowl in the same league as a Brunswick staffer;  he uses pin-above and pin-below layouts in his asym Zones, and he strikes at will with them, so it must be OK...

Hmm, I know about the warranty issues (at least 1" distance if the pin to any hole). But we were just wondering why this Strike Zone will not hook? I do not know my friend's PAP, I guess pin to PAP is between 4 and 5" - not a too weak drilling. The ball is 14 lbs., quite light and easy to handle.

At first we thought it was him, because he plays quite fast, used to have a low track and did not generate much revs. That's why he bought this hook monster. When he was disappointed, me and friends also tried the ball - and it moved surprisingly weakly for any of us!? Strange, strange...

Well, if any body has some more pin positioning experience on the asymmetric Zones, please post it. Thanx!

its possible that you dont have enough oil on the lanes to use the strike zone.
its designed for that condition.
its possible that its losing all its energy in the drier heads/midlane before it even gets a chance to hook on the backend.

Just as bracket creep says the drilling sheet I got with my Impulse zone has two drillings over the bridge...and two to the side of ring.

Mine drilled over ring...with mass bias Strong is VERY strong.

When you say mass bias next to thumb do you mean positive side or negative side of thumb.

The drilling sheet I have said no mass bias positions on negative side which is becoming more common with the stronger mass bias balls of today.

Triple X, Vertigo and all new Vanguard core Morich balls say positive side only!  This is VERY important as I have a friend(top morich guy) drilled his WMB like his TA and it reversed flared.  He redrilled mass bias strong...and has a smooth carrying MONSTER!!!!

I am impressed how much move I get from a slioghtly higher rg ball with a coverstock designed for smooth.

"PS I drilled my TA very similar to above and baby...it moves but I would expect just as much from the strike zone!

The word is that these very high mass bias balls...they can get confused if mass bias is too close to track and will reverse flare.

If you must drill like that there are many lower mass bias balls that are still mass bias and plenty strong.

Examples...all non vanguard core balls from Morich.

X factors...deuces...Drives and Alter Egos from columbia.

Note you can on the Bruswick zones put mass bias under thumb!

REgards,
