$200 ball at a $120 price point.

I drilled it over the label pin above the fingers cg kicked a little with no extra hole. Bowled late shift after a party and and a commercial league. I was worried that there would be too much carry down for this ball.  BUT NOOO!!!!!!
The Boom made a consistent and strong move to the pocket.  The pin carry is phenomenal. Once I relaxed and let the ball work I was very pleased with a 195-266-260-721 set.

I drilled a Boom for a 200 average woman.  Her reaction was quite good.  Strong move to the pocket.

Overall this is a very strong pearl reactive.  I would place this ball in the same performance category as balls costing $150-$180.  Not for heavy oil by any means but definitely good for all releases and styles on almost all house conditions and some drier Sport conditions.

This ball is truly a best of breed!

If you bowl on lighter oil volumes which supply the midlane to the ball and you are getting an over churning midlane with lots of 4 pins and 10 pins and struggle to strike.  But you feel the shot needs some backend pick up this beauty.

Take this ball put your favorite near stacked drilling.  Small kick out stacked label whatever this ball has a light touch of midlane.

This ball is the new improved blue pulse for today's slicker oils but still light volume.

Drilled 4 1/2 X 4 (stacked for me) pin and cg up a little on this 2 3/4 inch pin out ball.

This ball is too be fit between your Silver Streak Pearl, Fuze Ignitor, Ego, or other high flare pearl ball and your Sonic X pearl(for the truly dry short pattern).

This ball will give you area if the Sonic X pearl won't and simplify your game if the shot doesn't allow you to open the lane up with the high flare babies above.

The perfect combination of backend and length for a very light volume 40 foot pattern.  The Sonic X pearl the perfect combo for a light volume and about 32 foot pattern.  Get it!

This could seriously raise my average on the near dirt I'm throwing on by 30 pins.

Note the beautiful thing about these balls is the little bit of midlane the core supplies is Just right!

One of the best balls in the game for when your proprietor wants to trick you up and make you look like a fool.  Now he's going to have problems.

Go outside the oil line play some dirt and get some attack angle!

PS I'm ordering a backup!

It may seem strange to review a ball that has been on the market for a year-and-a-half and probably won't be available much longer, but I got this ball fairly recently and it does just what I want it to do in a niche that is hard to fill.

I'm a tweener and have the usual problems associated with being a tweener.  I have several balls that are meant for use on medium conditions.  They are similar, but different enough to give me several options for finding the best carry on a given night.  I also have a few balls for dry conditions.  My mirror polished Sonic X Solid is excellent on lanes that are quite dry, and I have a Slate Blue Gargoyle for toast.  The problem is that there is a substantial gap between the medium condition balls and the dry condition balls.  This is when the lanes have transitioned--and are still transitioning--and I am forced into a deeper position than I like and am losing carry because of it.  The lanes are, however, still not dry enough for me to get a decent move out of the Sonic X.  I have always had trouble filling this spot in my lineup.  Everything I have tried for this spot, regardless of drilling or surface prep, has always been too much or too little.

The Sonic Boom fills this spot brilliantly.  I have a 15 pounder drilled with the pin an inch-and-a-half from my PAP and the CG in grip center.  This is a low RG drilling, but this is such a high RG ball that even with this drilling, it is still a higher RG piece for me than anything else I have except for the Sonic X.  I drilled it like this to minimize it's already minimal flare, but to create a smoother move than what I would be likely to get from a higher RG drilling.  Besides, I've used this drilling successfully before.  High RG drillings give me a sharper move on the back than I like.  After trying the Sonic Boom in box condition on the recommendation of my driller--whose opinion I respect--I found that my initial impulse to put more shine on it was correct.  What I have arrived at as the best prep is to clean it with Renew-It, which shines it a bit to start with.  I then do all six sides with a dollop of Storm Step Three mixed with a dollop of the regular black label Black Magic.  After that, I go over it again with Renew-It.  The last run of Renew-It takes off a bit of a haze left by the polish and leaves the ball looking shinier and feeling tackier.  

The Sonic Boom fits my transition ball niche perfectly.  This may not be as critical a spot for some readers as it is for me, but a lot of tweeners will probably recognize the problem as being as difficult for them as it is for me.  Last Friday, my medium lane equipment had forced me up against the ball return and my carry was getting bad.  Except for a cranker and a high speed player, the rest of the bowlers on the pair were experiencing the same problem.  I pulled out the Sonic Boom and moved my feet back 4 boards to the outside and moved my mark one board back outside and got a nice long skid with a late midlane rev and a smooth arc to the pocket.  The carry was excellent and I had a good string going when the ball didn't come back from the return.  

The ball return had grabbed a couple balls by then, but I was the first to call the counter.  They sent a mechanic back behind the pins, but it was quickly obvious that the balls were backed up somewhere near the mouth of the ball return.  By the time he got up there and took the thing apart and dug out the three lost balls, about 8 minutes had passed.  The ring finger hole on my Sonic Boom was smashed.  Coverstock material was crunched up into the ring finger hole and the bridge was broken.  I was aghast because the ball was just what I needed at a difficult time in a close, important game.  I went up to the counter and the manager managed to crunch the material around so my ring finger hole (I use inserts) looked about normal.  He then used a glue made by Loctite that is similar to the usual type of Superglue used on inserts, but it sets a bit slower and squeezed a bunch of it into the smashed up mess around the bridge and ring finger hole.  It took only a couple minutes to set up and it seemed that it would hold together for the rest of the game.  (The center agreed, of course, to take the ball afterwards and have the pro shop drill it out, plug it, and redrill it at no cost to me.)  By the time I got back to the lanes, about 15 minutes had passed since the initial problem and everyone was waiting for me.  The other team was probably aggravated, but no one said anything because they knew I was already pissed and pouring fuel on the fire would be unwise.  (The league president was on the other team.)  Due to the lost rhythm and residual tension, I spared a couple frames before getting back my strike shot, and finished up with my best game of the night and the best game on the pair that night.  

That last little anecdote isn't really part of the review I guess, but I enjoyed telling it and thank you to anyone who stayed around long enough to read it.  The pro shop--which is new in this particular center--did a good job fixing the ball, and they reproduced my proper pitches.  They didn't know it, but I was testing them to see if they'd get it right, and they did.

The Sonic Boom is an excellent ball.  People with hand will probably be able to use it on a medium condition, and some others will probably be able to use it on a quite dry condition.  I would say this ball would be an excellent choice for a tweener who is in a bind during the transition game.
