Coverstock on Black Sparkle Particle Power Groove?
« on: February 03, 2009, 06:40:46 PM »
Hello,

just a question concerning the discontinued black PG Particle: does anyone know which coverstock was used on this piece, and/or anyone has a link to its drilling instructions PDF?

On big B's site, this specific file is missing (there's just the file/info about the Plum Pearl PGP, which is suppused to have the Navy Sparkle Fuze's coverstock in a pearl version?), and I'd like to assess how strong the cover could be?

Thanks a lot in advance!

according to www.bowlingballreviews.com  this ball featured brunswicks low load particle coverstock. the power groove series also featured the differential increasing side cylinders(DISC)in addition to the tradional pancake weight block. any drilling pattern that you would use on a brunswick symmetrical ball will work fine.

I think it's the coverstock from the Blue Denim Quantum.  I have a black PG, I never really liked it that much.  It's got about a thousand games on it, but if you pay for shipping, it's yours.

Thanks a lot. I also found hints that it is the Navy Sparkle Quantum's coverstock - is this more of a urethane coverstock base, or already a reactive coverstock?

Thanks for the offer - I just got a PGP from ebay (1st drill, already plugged, but probably some years old and with some battle scars), and wonder how to set it up.
I will probably polish it and put a simple label drilling on it, as a control piece for medium and less conditions, but the coverstock (and its potential strength) puzzles me a bit.

Dizzy,

  Don't be fooled into thinking that this is a weak ball by any means.  Had one back when they first came out and in the factory finish it would handle more oil than we EVER had.  About the strongest ball in my bag.

  Did a little more research and I think i found the old Brunswick PR and spec sheet for it, at least I think this was the one they had on it.

 
Plastic slips. The Groove grips. And grip is exactly what you need to improve your game. When you’re ready to step up from plastic, get in the Groove.

Want more hook? Move all the way up to Proactive coverstock technology. Compared to Reactive, Proactive coverstock technology increases hooking action in the oil by adding texturizing particles that create a tread-like surface that tractions through heavier amounts of oil, increasing friction and hooking action. Like Reactive coverstocks, Proactive coverstocks can be sanded or shined to create large differences in hook potential. Proactive coverstocks also respond less violently to dry lane surfaces than Reactive coverstocks, creating a smoother, more arcing ball reaction with more control.

Coverstock: The Black Sparkle features Brunswick’s popular Low-Load Proactive coverstock. First used on the Navy Quantum, this Proactive coverstock is the strongest ever used on a Groove class ball.

The Core: The Black Sparkle introduces Brunswick’s new DISC (Differential Increasing Side Cylinders) core technology which provides:

The largest track flare potential of any ball in its class
Consistent track flare potentials at all weights from 12-16 pounds
Larger, more consistent pin-out distances at all weights from 12-16 pounds
A more driller friendly design. The precise geometric placement of high density side cylinders maximizes the increase in Track Flare Potential while maintaining perfect dynamic symmetry for easy drilling.


Coverstock: Proactive: Low-Load
Weight Block: DISC (Differential Increasing Side Cylinders)
Finish: 400-Grit Wet Sand
Color: Black Sparkle
RG Max: 2.708
RG Min: 2.667
RG Diff: 0.041
RG Avg: 8.2
Durometer: 76-78 Rex D-scale
Length: 70 on a scale of 25-235
Breakpoint Shape: 60 on a scale of 10-100
Hook Potential: 115 on a scale of 10-150
