Reaction Characteristics
The Ultimate Inferno is a heavy oil ball designed for bowlers who prefer Reactive over Particle coverstocks. The Ultimate Inferno uses the same core as the original Inferno but combines it with a solid 800-grit dull version of Activator coverstock.

Compared to the original Inferno:
-The Ultimate Inferno will match-up better to oily lane conditions, longer patterns and heavy carry down.
-The Ultimate Inferno will match-up better for bowlers who struggle with excessively long ball reaction.
-The Ultimate Inferno will match-up better on heavily oiled - over/under lane conditions.

Brunswick’s new Activator Coverstock has quickly established a reputation for excellence in ball reaction, durability and longevity of ball reaction. On the lanes, Activator Coverstock is clean through the heads with excellent mid-lane recovery and a strong arcing back-end reaction that creates powerful pin action. Owners of the original Inferno have reported that it requires less frequent resurfacing and rejuvenations and is more resistant to cracking than other reactive coverstock balls.

Utility
Out of the box: The Ultimate Inferno is an ideal heavy oil ball for players wanting to use a Reactive coverstock.
When shined: Using Brunswick’s Factory Finish High Gloss Polish the total hooking action of the Ultimate Inferno can be reduced and the arc made more skid/snap.

Reaction Setup
The Ultimate Inferno can be drilled using the standard drilling techniques developed for two-piece balls, see the included drilling instructions for reaction characteristics and layout details.

The Ultimate Inferno is finished with a dull 800-grit surface finish which increases its hooking action in the oil. Dull surface finishes can sometimes hook too early resulting in reduced backend reaction and hitting power. To increase length, polish the surface with Brunswick’s Factory Finish High Gloss Polish.

Ok everyone a bit about me, lefty, md-low revs med speed stroker. Mostly stay behind the ball, but can put more turn on it if the shot calls for it.

Ball came in 16lbs even 2-3 inch pin and decent topweight.

Had the ball drilled for midlane. Not much on drilling specs but pin below ring finger and cg kicked out a bit. Small deep weighthole almost parallel to the center of my grip.

This is yet another great ball from Brunswick. On the right condition this ball is BETTER than the origional though with my drilling and the box surface it is not as versatile (i sanded my origional inferno). This ball, for strokers WILL NOT be a ball for floods. It will move on heavy oil, but wasn't as consistent or strong as my throttle (see profile for info on that ball). It is more at home on heavier mediums though those with less speed or more hand may like it better on a flood than I did.

Also, this ball is not for dry conditions. It will not hook on dry, so if your ball isn't hooking like you thought it would, the lanes may in fact be too dry. This isn't a ball that will hook the lane on dry lanes, it will roll out, at least with my drilling. Use this ball on the right condition and it's your best friend, on the wrong condition it will give you headaches (aka 9pins) all day long.

This ball is at home on flatter patterns, and heavier mediums. It is predictable, with a nice roll, and doesn't force you to play out to the dry on house or wall shots with decent oil inside. You can play in the oil and still have a good entry angle. Carry is up to par with the origional, both of which are two of the better carrying balls i have thrown.

Overall this is a great ball, but a bit too condition specific for my tastes. It will still stay in my bag, but i'd love to be able to use it more, one of those balls you don't wanna put away. I'm probably going to polish it in hopes of it being more versatile. This will be a great ball for most bowlers, i believe crankers will like it on heavier oil in floods, and it's a great alternative if you don't like particle.

If your looking to fill a niche in your arsenal this is a great ball to do it with, you won't be dissapointed. In turn, if you usually bowl on drier lanes, you probably won't like this ball.

I'll update after i put more games on the ball and/or polish it. Until then good luck and good bowling to all.

When all else fails, become a lefty

I bowl at a house with a very flat, slick oil pattern.  The place also has very weak backends, which can make carry really difficult at times.  In fact, last week, I left 15 ten-pins during my league set.  I had the local pro shop guy drill me an Ultimate Inferno to see if it could help me open up the lanes a little bit and improve my carry.  I was very impressed with the ball.  My first league set with it was last night; I had 242, 228, and 300.  The ball rolls clean through the heads and really stands up and faces the pocket down the lane.  I have been throwing an X-Factor Re-Loaded most of the year, and the Ultimate Inferno is a great deal stronger for my game.  I have a medium-low track and a high rev-rate.  The drilling is number 2E on Brunswick's Ultimate Inferno layout chart.  I did polish the ball up - I can't imagine how much it would have hooked if I had left it dull.  I would definitely recommend this ball.

my first post

The UI rolls real heavy in the mid and keeps moving.  As far as I can tell, there is no way that I can use this ball any houses around me unless there is a decent amount of oil, REAL DECENT.  Other than that, the only thing that I dislike is that I cant play the track area because it just burns up way too fast.  Of course you shouldnt have to anyways.  Enjoy using it, I know I do

15 lb ball. Pin 2-2.5 inches. Drilled aggressively.

I am a medium-rev bowler with a high track. I have had this ball hook a lot on normal house shot conditions, but if you have a similar bowling style to me and are looking for help on a flooded condition, you won't get much. I learned that one fast. Although in it's defense it did eat up the oil like crazy and by late in game 2 I was getting some decent hook to the ball.

Cleaning this takes some good effort. After each night bowling, it takes at least a full washcloth (front and back) and quite a few squirts of Ebonite Powerhouse Energizer cleaner to get this ball clean. I'm at 19 games now with this ball and at 50 games I'll soak it in hot water and Dawn to get the rest of the oil out.

All in all, I love this ball. I am striking a lot more often with this ball than I did before with my Illusion ball - which is now my spare ball.

Drilled it yesterday before a tournament which i didn't need it for, but i was meaning to drill it for a week.  Pin under the ring, cg just outside of it.  1 inch weighthole about an inch and a half below the midline on the val.  Balls is exactly what i love.  Great midlane recovery, continuous arc on the backend and explosive hitting power.  Creates room in oil, and reacts hard off the dry.  Carries off hits great and sends the crowd pleasing messenger with authority.  Can't wait to use it on my sport shot league.  Right now it is close to my best ball only to the original x-factor.

I have never thrown this ball, however, I have seen people throw the ball...

And I have VERY mixed reactions. The ball has the most aggressive move on the backend of any Brunswick ball that I've seen in sometime.

On the flipside, I know someone who gave up on the ball after two nights. He just practiced with it twice then decided to give it away -- he liked his Full Throttle so much better that he bought a second one... so who knows?

I drilled my Ultimate with the 3.7 oz TW drilled with the 2E drilling layout. This ball is great for medium to oily conditions, and it hits and carries like a monster! I can throw it from a variety of angles, and I don't throw with a lot of revs. This ball really needs oil, but it has burned out for me only once. Great ball 9.5/10, my favorite ball along with my Demolition Zone.
