Need to redrill my Vapour Zone, but how?
« on: June 14, 2007, 01:42:20 AM »
I bought a Vapour Zone to compliment my Absolute Inferno. My intention is to use it when my A.I. reads too soon and lose energy on the backend.

My V.Z. does clear the heads better but I find it to be angular. It hooks more than I would like and have a hook stop look. I plan to redrill it and what I hoping to get is a smoother and more CONTINUOUS reaction and perhaps covers less boards.

Suggestions please?

Currently, my A.I. is drilled pin below bridge (pin to PAP roughly 4 5/8) with small balance hole; my V.Z. is drilled pin above bridge (pin to pap roughly 5) with mb on my VAL with a 57/64 balance hole 2" deep.

Thank you.

Would the Classic Zone be a better choice?

The VZ is designed to be slightly longer and more angular than the AI.  Your "intention is to use it when [your] AI reads too soon and lose energy on the backend" and that pretty much means "longer and more angular".

The hook-set reaction is typical for layouts with the MB swung out to the VAL.  If you want to re-drill it, move the MB closer to the thumb, even under the thumb.  I wouldn't put it on the negative side, that tends to do goofy things with strong asymmetrics like the VZ.

If you wanted a step below the AI, I would not have taken a VZ since it uses the same coverstock, even the same surface, and has a basically more angular core. I guess the ZC would have been a better choice in the first place, more basic length, but potentially also pretty flippy.

IMO, the current drilling on your VZ should yield the reaction you are looking for - but bringing the MB closer to the thumb would be the way to go.

Maybe you can try some surface changes on the VZ first. Polish could be worth a try. Activator+ is known for its nervousity under full polish, but it might help setting the ball apart from your AI as it is. Maybe a fine basic grit plus a slight hit with polish will do the job.

Another thing could be a deeper balance hole, if static weights permit this. You could tame down the overall hook and surely the breakpoint shape a bit and avoid a complete plug job.

Thank you for your suggestions. I don't think there is much room for me to manipulate the balance hole. I'm quite keen on the idea of redrilling it. It would be a good exercise for future reference.

Here's what confusing me:
On paper, a stacked drilling(placing the mb midway between thumb and val) produce the sharpest breakpoint - which is not what I'm looking for in this instance.

By placing the mb towards the thumb(not beyond, apparently, goofy things would happen if one does) will produce a smooth reaction, which is what I want in this instance.

So, at what point on it'd be classify as more like midway or towards the thumb? Smooth is the opposite of sharp right??

In your opinion, the hook-set reaction is due to the mb being placed on my val? Does it work the same for all asymmetrical balls?

Thank you very much.

I believe what tends to happen with strong asymmetrics drilled with a negative MB is that the flare can get reversed and if you track high, clip the thumb hole.

In general, asymmetric layouts do the same thing for all asymmetrics, just like most symmetric cored balls use the same basic drilling theory.  The extent of the effect may be different depending on how strong the asymmetry is.  Strong MB balls usually have a greater difference in reaction than weaker MB balls with the same change in layouts.

Also, as I mentioned, the pin is under the bridge on my VZ at the moment which means that at best the mb is straight down and cannot be swung toward the left or thumb.

Could you clarify further the three main different mb location/reaction is refered in relation to the pin(left of, straight down, and right of) OR just the visual position(next to thumb, midway between thumb and val, on val) regardless where the pin is?

I hope my question make sense.

Correct, and this should be kept in mind when a ball is set up. With a strong MB you emphasize the desired reaction, the core quickly moves into its final stable PSA position. Therefore, a strong MB ball can be the ticket if you want a certain reaction, strong and stable, but can also fire backwards because the reaction "pattern" can be quite rigid, and weak asyms or syms can be the more versatile solution.
