I drilled this with the 4x3 that I like on most Storm reactives.  I required a little more kick out of the cg than usual to get the mass bias to the positive quadrant.  I ended up with more of a 9:30 pin to cg that would cause high track players or guys with lots of hand to flare over the fingers.  I expected the ball to roll much like my Trauma, but start a little earlier.  The first time I tried it on anvil lane with heavy long oil the mattte finish gave me a much tamer look with no sharp break point.  I purposely jammed the ball into the oil and didn't look for any dry area.  The carrying response was excellent on what appeared to be weak half pocket hits. I used it in league in another anvil lane house, this time on a tour pattern oiled 29 feet and buffed to 45.  My carry was more spotty, but the strikes came in bunches along with the 10's.  The 10's were all ringers, as a result of overpowering the pocket with a little too much ball speed.

In summary this one is a keeper.  It may be more versatile than my Trauma, even though it is more aggressive.  Also for you straighter players who stay away from Storm because you don't think you have enough hand this would be a good ball to break the stereotype.  The ER is great when you stay behind it with a little bit of hit on the upswing.

drilled rev leveraged

i have med-high rotation, high track, 17 mph, 16 revs

this is by far the most agressive ball i own - noticabley more than my silencer, and my el nino 2k

the ball gets good length and then makes an aggresive move for the pocket

i have found that this ball works better when i slow down and swing it.  otherwise i dont get much recovery, or indeed much backend.

the best thing ive got for heavy oil

this ball is also rev-sensitive, and rotation sensitive, making it unpredictable or quite versatile, depending on how consistent you are.

definately a ball for the seasoned bowler, but if you can controll it, it can give you a decided advantage

Two words....GREAT BALL. The out of box reaction on this ball is great.
The pin is out 3 inches below my index finger. This ball has great lenth
with a powerfull snap torwars the pocket, don't even think about using
this ball when the lanes are scorched, otherwise another great ball by
Storm.
Rating: 9.5/10

Thank you for Reading this review.

The Trend for Ball Manufactures end of last year and now into this Year have been Balls that hook a lot overall but still clear the heads cleanly. Examples of others balls that have this reaction are the Apex Family, the Rock Family, and now the Trauma ER. This lightly sanded (around 800 grit) Reactive features a large core and coverstock that was designed to leave a wider footprint in oil. This should allow this ball to hook more in the heavier oil patterns.

My Tester for this ball was Tom Jones; known to us by T.J. T.J. is a lefty “Powerstoker”that likes to cover some boards. He is not the classic left-handed that plays down and in. More of a modern contemporary game. We drilled the ER with a Pin Out 4” and positioned it 3 3/8 from his P.A.P. We placed the Mass Bias at an 80-degree angle. Tom bowls at 3 different houses. Two that are wood and one that is a Synthetic Panel.

At all three houses the Trauma ER has a strong overall hook but is different than most reactive’s in regards to the ball’s last 20 feet. This ball makes more of a snap reaction where the Apex’s and Rock’s are a strong arc. This ball has a strong continuation into the pins with an explosive hit. It does not hook overall as much as a Heavy Particle ball like a Monster, or HPH Family but does out hook an Apex by a few boards.  The Coverstock is easy to tweak for different conditions, but we have found that the ball tends to want to come back to the “Out of Box” condition. If you sand it with a green Scotch Brite Pad with the 3 game period the ball will smoothen back out to the 800 sand finish.

Other slight negatives is that the ball reads the oil and dry quickly thus making it harder to control on some conditions. We tended to see a little under/over reaction at times.

Still The ER is well worth the $200 plus price range and is geared for all types of Bowlers with the Correct Drilling on Medium to Oily Conditions. If you want Raw Power and Hard Hitability consider this Latest Product from Storm as your choice.

Thank you for reading this review and best of luck in your bowling endeavors.

This is my second review of the Trauma ER.  The ball (out of box condition) works very well on medium lane conditions, but I have encountered some heavy oil with carrydown in league and wanted to see what this ball could do.  I tried bowling with the Trauma ER (out of box condition) and it wasn't quite strong enough on the backend.  The ball just would not drive through the pocket due to the carrydown.  I switched to my Colossus (400 grit finish) and did not have a problem destroying the rack.
 
I returned the next week with my Trauma ER, however this time with a 320 grit sanded finish.  The lane conditions were very close to the previous week (heavy oil with carrydown).  The backend reaction from this ball was nothing but impressive.  While the other bowlers were complaining about the lanes ("My ball ball just won't come up... There's too much oil on the lanes...), the Trauma ER was hooking with authority and throwing messengers around like there was free hook on the backend.

I am very impressed with the Trauma ER.  Don't be afraid to change the coverstock to match your bowling style and the lane conditions.

had regular Trauma but was looking for sometthing to help out when a little slicker.pro shop told me he just took in a 15lb. ER with 4.75 top weight with 4'pin. told him drill it. pin above fingers and shine it. ended up with leverage drilling and 2.75 top weight.ball is a monster.turns corner hard and just keeps going. been holding 207-208 avg all year but 2 week with ball shoot 290-298-237=825. been with Storm balls for 3 years now and i figured why change now. give this ball a 10 outta 10.

i bought this ball this evening and can't wait to try it out wif my bowling teammates, on the reviews some gave a 10 out of 10. This makes me can't resists to getting the ball immediately from the pro-shop. At a 15lb, i believe this ball will surely hit the pin hard in the backend and delievers great strikes on even oily conditiions.  A must have ball for oily conditions
