Pin-PAP 3 3/8"
A little info aboot me:
Revs: 300-350RPM estimate
Ball Speed: 15-17mph
PAP: 5 1/8" over 1/4" up
I tend to prefer particle balls as they give me a much better look on the lanes with my lack of handedness.

Conditions: Everything from THS to PBA Pattern E.
Surfaces: Mostly synthetics, rarely see wood lanes anymore.

This ball in box finish(high gloss polish) is great for medium to medium/heavy lanes. With this drilling the ball for me clears the heads very well with the polish but gives a strong move on the back but it is not jumpy. The particle cover gives an awesomely predictable move on the back without losing any power at the pins. The activator cover responds very well to surface changes and the Zone core lends itself to a variety of drill patterns for different looks on the lane.

Hook: This ball is best suited for Medium-Medium/Heavy conditions. When the factory polish is removed, the ball would still be best for Medium/Heavy. I still wouldn't call it a heavy oil ball. This ball for me is a tad earlier than my Delta 1 (drilled very similar) and a touch less on the backend. 8/10

Control: The Impulse Zone is great for reading the lanes as it does exactly what you want it to do. The only ball I would rather use to read the lanes is my ageless wonder, the Rock Star. 8.5/10

Hit: I want to say this ball hits harder than anything I own yadda yadda yadda like all the rest of the reviews, but I won't. This ball hits as hard as you want it to. Throw the ball good and it will carry, throw the ball like a wet fart and it will hit like one. Most bowlers can tell whether or not a ball is going to be good or not. This ball does enjoy keeping pins low and once and a while even a fine messenger (I don't usually send messengers around). 9/10

Overall: I always wanted to get my hands on a Fuze Eliminator as I saw many good bowlers enjoying success with that ball. When I heard the Impulse Zone was pretty similar to the Eliminator, I knew it would be a good ball for me. As it turned out I was right and am now waiting for some funds to start adding to my collection of Brunswick and Zone pieces. I use this ball when my Delta 1 starts acting a little squirly or I need something that will turn the corner earlier than my other stuff. With the games I have put on this ball I have learned one thing:
Activator Coverstock= Good
Mid Priced Zone Equipment= Gooder
Add Particle= Goodest for peoples like me
Impulse Zone= Hooray!  

Thanks for taking the time to read my review, any questions feel free to ask.

Stats in profile:

Specs: 15lbs
Pin: 3-4"
Top: standard
Box finish

Because I picked this ball up specifically to toy around with, I allowed my driller to go with whatever layout he felt would give me the reaction for which I was looking. That reaction, basically, was for the ball to read the lane early but then remain very smooth, mild, and consistent down the lane. In essence, a ball for smoothing out severe wet-dry.

When all was said and done, he placed the pin under the bridge, the cg down and to the left and the MB in line down and left of the thumb hole. We left the ball in box finish.

Results:  I haven't thrown this ball a great deal just yet, but I think we definitely succeeded in giving me a look that I didn't previously have in the bag. With this drilling, the Impulse is tame the whole way down the lane. It seems to enjoy being played very straight up the boards. On our freshly oiled house shot, which usually serves as nothing more than a standard medium volume wall, the ball reacted best when thrown up seven or eight directly with the boards. If I leaked it a board or two further right, the ball would read the pattern sooner but still would not over-react on its way to the pocket. If the ball was pulled in just a bit, it picked up the roll and tried to fight its way to the hole. Once it got there, it was simply a matter of whether or not the 10-pin would snap out.

Just for giggles, I attempted to move deeper inside and give the ball more hand. To my surprise, the ball would make a fairly hard move if I truly wanted it to. I was able to play as deep as third arrow out to around the 3-4 board and get it back to the pocket with some power. The ball didn't seem to like this path nearly as much as the straight approach, but it did its best to accomodate what I was asking of it.

Overall, I think this will have to be a niche ball. I don't see it having a great deal of usability on a day in and day out basis, but for what I drilled it for, it  should shine when called upon. With this drilling, the ball is very stable, predictable, and it provides a pretty solid punch.

I'm not really sure how this ball would react with a more traditional drilling. I think we've all heard mixed results. What I can tell you is that the ball can do what you want it to do provided you plan things out. That's the key to matching up ball to bowler: figure out what you want the ball to do and on what conditions you want it done. Once you've got that figured out, let your driller lead the way. That's what I did, and I think it has led me to another very nice piece of equipment.

I've had a few bad experiences with brunswick gear so I was a bit reluctant to get this ball even though I liked everything I had seen and read, I could see this ball sitting at the top of my arsenal.
I bowl around 15-17 mph, high revs, pap 4 3/4 over 5/8 down.
The ball came 2 1/2 inch pin, 2.5 topwieght.
I layed it out 5" pin to pap at 25 degrees, pin ended just below ring finger, I put the balance hole on the pap and brought it back to 1/2 positive.
On a typical house shot fresh oil I was playing around 4th out to 6-7 board, this ball for me revs up like a nutter with a very readable transition and a monster finish that pounded it way through the deck.
I bowled with it for the first time in our sunday morning pot games, straight out of the box 265 for the first pot, two games later 254, so its starting to pay for itself allready.
Great ball, I dont know if I will try other brunswick gear just yet, but this ball is a winner.If you can get this ball cheap, try it.

Perfection is NOT attainable, but if we chase perfection we can catch excellence...

This is a very smooth arcing ball, with decent hitting power.  This is the first ball out of my bag on a fresh league condition.  I put it up as soon as the lanes start to transition and I am forced to move in deeper.  Once this happens the ball tends to be a little squirty (doesn't like the oil that well) and tends not to carry the corners.  If you are looking for a smooth arc with some pop, this will be a good ball.
