We drilled a 3 piece Gyro for broken down conditions and had some interesting results.

We drilled the Gyro in it's out of the box shell, with the c.g. 2" from the p.a.p.  With this layout an extra hole was required which we placed 6 3/4" from the grip center.  This ball actually surprised us with it's total hook.  We were throwing it along side a Lightning Storm and a Code Red S.E.(with the same layout) and didn't see a big difference in the number of boards covered.  As the lanes broke down the Gyro maintained it's length but backed off if there was any carry down on the backend.  Since we were looking for less hook we decided to punch a second ball out with a different drilling.

With the second ball, we put the c.g. 6" from the p.a.p. under the fingers.  We got even more length with less movement on the backend.  We had exactly what we wanted on lanes where length was the problem with our other equipment.

It's important to note that when using this type of low end equipment, you can't expect the same explosive carry as you would from 'premium' models.  This ball (or any 3 piece) should be reserved for conditions where the more powerfull cores and coverstocks are too much.

Overall comments:  The 3 piece Gyro will provide a stronger reaction that you might think, given the right lane condition and bowler style.  In order to get the ball to react on the lanes it was intended for, label drillings are the best option.  The carry, while not explosive is better than you might expect.  This is the kind of ball that you may only use a few times a season but it will keep you in play on those occassions better than most other reactive balls.

Well, all i can say is that this is a great ball.  I have had the green pearlized Gyro for about 8 months now and it has tranformed my game.  Just before i got the Gyro my average was a 118.  After just 1 month of practice with the Gyro my average jumped to a 160.  The ball has given me a controlled hook that penatrates into the pocket at a perfect angle.  Anybody who says this ball doesnt hook doesnt know how to throw one or doesnt have it drilled to hook.  My ball is drilled 3/4 oz. side weight and for me it hooks a good 10-15 boards depending on the lane condition.  If you have never had grips before and you want to try, this is the ball for you.  It is so controllable it is unbelievable!  This ball will transform your game!!  It also is ideal for spares!  Get this ball, you'll love it!

Hy folks. Had a Gyro Reactive Pearl for 6 years . I can be short about this ball. When you don't want to throw a bowlingball straight anymore , this ball ISN'T the one to go for. I threw it at various manners (degrees) , different speeds , different lane-conditions... nothing really works.You have to force yourself physically to make it hook 5 boards. Useful as a spareball , non the less. I've just bought a Ebonite Pantera and a JackHammer emerald pearl. As a student I hadn't much cash so I had to wait till I could afford a decent ball. With the Gyro I accomplished an average of about 170 in my league (throwing this 13lbs ball at about 19mph) , but that will probably be the maximum I can get out of this ball. Hopefully my new Ebonite Pantera will give me the joy of hooking a ball.

Had this ball drilled 4x4 with the pin over the ring.  This is a great ball when it seems that there is no oil at all on the lane, it doesent happen often but when you have the day that you cant keep anything else on the right side of the head pin you would be glad to have it.  I throw this ball 19 swinging out to the ten and having a medium ark back to the pocket.  I would recomend this ball to anyone as a dry lane ball or to any beginer bowler who is just playing a small hook off the corner.

This review is on the Gyro Urethane with Particle, Not the reactive.

Set the ball up with cg/pin on PAP, 9" hole in line with center of grip and Pin to take out bottem weight and finger weight.  This is one aggressive cover.

Used on house shot 38', flood in middle, 5-8 units outside.
Ball does not skid much at all.  Just gets into a hard roll with small arc.
Hit was good.  Just soft enough to carry the back row good.

In box condition played dry real well also.  Didn't want to roll out.

If I can, will try to find some oil to try it in.

I think this would be a secret weapon on a chopped up condition.

Everybody could use a ball like this to compliment the more aggressive polished shell bowling ball. I have my ball drilled in a Low RG-ARC drilling. The Pin is set 2 1/2" from the PAP in a 3:00 direction from the CG. The CG is set underneath the ring finger on the grip midline. The ball delivers a very smoove controlled arcing hit to the pocket keeping the pins low with a lot of pin action.

I had the Black Reactive Resin Gyro few years back.. dull surface..
rolled it with a lots of roll.. 10 to 10... then see the reaction..
BLast!!! Predictable reaction and always come in...
preferably medium to oily lanes... been always cleaning the oil of the ball after every throw...but it still picks the oil back again after again...
X X X X X X X X X Xxx
PeRfEct GaMe!!!

Scores don't mean anything...

This was my first reactive resin, 15 years ago. Had it for maybe a year b4 I got my Nitro R2.  Label drilled, no axis hole, OOB finish polished finish, then after a few years gave it a leverage drilling and hit it with 1000 abralon for more surface/reaction.

This ball was good for dry lanes. Nowadays with the soup they put out in most houses this ball probably would be useless unless on a very burned up condition or as a spare ball.  I had good success with it it was a very consistent reaction, little over/under, not a hard arcing ball by any stretch but hitting power was good, mixed the pins well and kept them low, great for intermediate players still learning to throw a hook or those with little ball speed.  I'd say it was definitely a good investment and step up from my Gyro urethane but I couldn't find a use for this ball today with the volume of oil that is typically used (back ends would have to be dry dry to get this to move much).  this is the perfect starter reactive ball.
