I have had this ball for several months now, and just realized I didn't write a review for it.  

I have this ball laid out with the pin beside the ring finger and the bomb in the strong position.

This ball is great for medium - heavier oil.  On the heavy-heavy oil this ball didn't move that much.  I have been averaging very well with this ball over the last couple of months and it have become the ball i use to read the condition with.

With the layout that I have the ball, it is clean through the heads and then gives me a smooth midlane reaction with a controlled move to the pocket.  When the heads dry out the ball losses too much energy up front to have the drive in the pocket. If I changed the box condition, and polished this ball, I am sure it would be a great ball for the drier shots.

I give this ball an 8, because I have been able to use it on a variety of conditions and think it would fit nicely into a lot of bowler's games.  I think that with the right surface adjustments, this ball could be used on almost the any condition.

   I am writing this review to update my experience with the Matrix Dominator.  The initial review was very positive and with good reason.  The first month I used this ball it seemed as though every shot that was flush in the pocket-carried.  

   The problem is that less than two months after drilling this ball, it seems to have ‘softened' and does not carry nearly as well as it did.  I have NOT put much faith in all this talk about balls "dying" but I must admit that this ball appears to have done just that.  Being a pro shop operator, I am able to maintain my equipment better than most but that has not prevented this ball from a noticeable drop in performance.

   Our shop has seen some similar problems with the Predator and Vortex III but we were attributing this to a lack of cleaning and maintenance.  We now are a little concerned that perhaps some of the Ebonite (and other companies) balls with thinner shells are more likely to lose performance sooner than those with thicker shells.  We are planning an experiment over the summer that will help us determine whether there is an advantage to thicker shells when it comes to life spans.  I will then post an update on the forum.

Drilled this ball last fall.  Drill pattern is a 4x4 as I drill all my eqipment with this initial layout so I can get a true comparison between equipment.  Initially ball was a little strong out of the box.  After polishing, ball was fantastic.  Ball cleared front part of lane and finished as strong as my intensity.  After approx 100 games, ball started losing its drive.  Track was getting a little burned out so I resurfaced the ball.  Since resurfacng, the ball is terrible.  Ball just has no zip on the back ends.  ust like previous reviewer, I manage a pro shop and my equipment tends to get a little more TLC then most.  Recommend any Ebonite equipment, just not this ball.

This ball was great when i first got it, heavy oil - no problem.
Had several high games with this ball.
After about 3 months the ball started getting weaker and weaker.
Thought at first it was me, i experimented with my other balls for several months comparing them on different lane condidtions.
Finally i soaked the ball to remove oil and resurfaced it. The ball was better but still didnt act like it used to. After about 6 games it was back to nothing again.
Have to say i really liked this ball at first but ended up being a big disapointment.
