I had this ball for about two months before it cracked around the pin.
Personally, I didn't like the ball. When I threw it box, the ball would hook in the heads. Once I cut it past 1000 grit (16 micron and lower), the ball would start to skate past the break. I never got a really good read with the ball, so I wouldn't recommend it to power players with higher ball speeds. I'm not posting a full review of the ball, as I don't think it would be fair.

Hi Everyone, this is my first review on this site, but I'll give it a go! I got my response at the end of May. It is the first really aggressive ball I have had, and when I say aggressive I mean it. Previously to buying the response I was rolling a 185-190 average. I have a basic hook style, and tend not to rev the ball too much therefore I have not gained a lot of hook from my previous balls. But the response doesn't need the revs because it will come back from however wide you roll the ball. But my average has dropped significantly since buying this ball to around 178-180. This I think is due to my lack of experience with bowling with ball which turns so much on a lane. I am only 18 and don't have much experience of adjusting my bowling ball surfaces.

Therefore, I am looking for some on advice on adjusting the surface of the ball to suit my style and lane conditions. Any knowledge would be greatly appreciated.

I have had this ball for about a week.  The ball is driiled for lenghth but stiil with a strong hook.  I have only had the chance to throw it on medium-medium heavy conditions.  Way to strong out of box.  Had it polished but it is still very strong.  I got this ball for heavy oil but haven't had a chance to try it there yet.  The ball hits very hard and the carry is good.  Can't wait to try it in the oil where it belongs.

I have been waiting for the last 3 months for my summer league
to finally near its end and receive my Trauma Response for bowling in
the league. Unfortunately, I have been very dissapointed with this ball
so far.  I got a 15 lb ball, with a 3.38 oz top weight and a pin placement
of 3.5-4.  I used the storm layout #1 with the mass bias on the perpendicular axis line (PAL).  I was told by the local pro that this was supposed to give me the earliest roll on heavy oil conditions and it has, but everytime the ball hits the pocket it has nothing left.  Based on previous reviews I was expecting this ball to come back from anywhere and hit like a ton of bricks but it hasn't.
I haven't been able to carry any light hits at all.  I was really suprised by this because I am a cranker who throws about 18-19 miles an hour and I usually put a lot of hand in the ball.  I just never expected this ball to be a dud except when hitting high flush.

i got this ball used by a friend who hated it. it has a 4 inch pin.

i drilled this ball the pin under the ring finger and the cg kicked out 40 degrees. with a 1 inch weight hole drilled 2 inches deep 4 1/8 down and 2 1/8 out from my axis. i tried everything with the cover of this ball i sanded it to different grits, i polished it but it still kept the genral reaction "roll, hook , hit like a marshmellow". this ball gets into a really heavy midlane roll. a lot of times it will roll out no matter how much oil there is. i dont recomend this ball to anybody.

This ball i think is the worst trauma ever made, i had it drilled 4x4 with the pin over the ring and the mass bias on the outside below the ring, with a leverage hole on the outside.  This ball while haveing its consistant hook from the time it touches the lane to the end,  it releses all of it's energy in the first fourty feet of the lane, to where when it needs to have a strong angle into the pocket it cant turn.  I recomend this ball to no one!  This ball is a better paperweight than a bowling ball.

OK well i just got this ball tonight, and DANG!!! i love this ball I dont know why people say they hate this ball i couldnt believe how great this ball got down the lane and turned and carried. OK well this ball has about a 2inch pin, which is under my ring finger, and the cg is almost straight under it, but it is slighty to the postive, so i believe it is close to 3x3, but not sure, cuz i have a tourpower drilled 2x2, and the pin/cg is closer to my pap. Anyways well this ball also has a polish to it also. I got this ball drilled tonight, and bought it used, had like 15games on it. I first used it in the 7th frame of the 2nd game, and at the time i was using my Trauma ER, which has a stronger drilling. But i figured that i would keep on using the same line, which was 20-10 on 41ft med oil pattern. And i ended up throwing the next 4 strikes with this ball, and had a 8 count in the 11thframe. And in the third game, i went a bit deeper, to a just inside 5th arrow out to 10. and well still had the same results, i ripped the pocket, the whole game. but did have two splits in the 8&9th frame, but still shot 216. I will say that this ball does seem to burn up the energy when it hits dry, but in my case that is good, cuz i have such a strong ball that i leave alot of solid 9's  and i did have two tenpins, tonight, and one 9pin, while using the Response. I will say that this ball will come back if you swing it wide, lol, i let one shot go way out to about the 5board and it came back for a big strike.  But enough about this ball for now, i really like this, ball, hehehe, i will review this ball tomorrow night when i use it for the whole 3 games and then be able to tell what happend on a fresh shot.

This ball came to me w/ a 5.5 in pin.  Not a good pin for a heavy oil ball.  I drilled this one 5x5 no weight hole needed.  With the longer pin it skates too long in the heavy oil.  On a typical house shot, It is a good hard hitting ball. It revs up early in the midlane and has a good hard arc off the dry. A very good ball but not the best drilling for my game.
