After more than 8 years of research and testing, Columbia 300 is proud to announce Catalystâ„¢ coverstock, and the EPX T1 high performance ball using this breakthrough technology. The first major innovation in coverstock formulation since the advent of reactive resin. If you are on wet lane conditions and looking to play the inside track, ask your Pro about how you can get more friction, more boards and more strikes with Catalyst and the EPX T1.

Patent pending.

THIS IS A FOLLOW UP FROM MY LAST REVIEW.IVE GOT ABOUT 15 GAMES ON MY EPX NOW AND I HAVEN'T SHOT LESS THEN 632 WITH IT.I DO KEEP IT CLEAN AFTER EACH DAY I PUT IT IN HOT WATER AND WIPE THE OIL OFF.SO FAR I LOVE THE BALL.GO TO CORPUS CRISTI IN TWO WEEKS WILL GIVE UPDATE ON HOW IT WORKED IN THE HEAVY OIL.

Well im back from Texas.I only threw 3 games with the epx and I had to leave family emergency at home and didn't do the doubles and singles.But the lanes were oiled just before our team event and this ball performed like a champ.Shot 620 with 5 opens.Could have shot better but like I said had other things on my mind.Im right handed stood at 15 board left side and took it out to the 1 & 2 board and was killing the pocket.Had 1 pocket 8-10 other than that the pins I left were because of me.When I hit the pocket the pins blew off the alley.Great Great Ball Love It.

I Bought it 2nd hand. Drilled Mildly REV Dominant with Strong Reaction.
I've only used this ball 2 times total of 8 games in a Sports shot. But I still have a mixed feelings about it. The First week it works on a flooded lane. It hooks compares to other heavy Oil ball. Then I decided to Deep it in the Hot water before the 2nd Week then the ball hits like a dart. I think I've just pushed the oil out close to the surface instead of totally draining it. Then Boiled it really really hot and drained the oil completely but Sport Shot ended and never played sport shot again. Damm! I'll sub next time just to try it.

A BIGGER ONE,EVEN LARGER THAN INFINITE!

SPECS: pin is below and left of my fingers mass bias is out about 2 1/2 inches and the PAP is about about 4 1/2 inches. small balancing hole to give it a little length

THS: 38 Feet light outside and med-heavy volume in the middle roughly oil 10-10 dry the rest of the way to the ditch.
EPX eats this pattern for lunch. The ball gets down about 35 feet then you can see the ball get ready and go left not a hard turn but not a smooth turn just in the middle covers alot of boards in a hurry I gotta make sure I stand well left and throw well right I really don't need to aim a whole lot I just look left and the ball pretty much takes care of the rest of the shot for me. EPX hits like a bomb pins just fly back and messengers are coming from the sky and the pit and the parking lot again this balls angle and power pins don't have a chance. Normal Line was like this 15-20 at the arrows and where ever I pleased at the break point as long as it was right of 15

MOUNTAIN BAY MASTERS SHOT: I used this successfully the first couple of weeks in the league when we had very heavy oil. Shot was like this, Heavy juice all the way across the lane very little anywhere you put the ball out of bounds 7 and out to the gutter. 41-43 feet buff to 45 or a little more. I have bowled on easier SPORT Patterns!
Like I said only a couple of weeks of use for this ball and it tore the shot to threads it is an oil eater of a ball. I would release at 14 and throw out to 5 straight into the out of bounds area and the ball would just bath in the oil then hook like monster once again the same turn as previously mentioned above and the same hit. It was like the added oil didn't even affect the balls performance it was still a killer. Other than standing a little farther right on the approach no real change was needed.

PBA PATTERNS: I only used this ball on the heaviest patterns and the ball was more than I needed I was often very far inside with the shots trying to keep the ball in oil long enough it was just sick. A note to those who are throwing the BIG ONE on the same shot '' Don't whine cause my ball hooks and yours doesn't.'' Once again when ever I pulled the ball out that same hook and hit if it wasn't so good I might get sick of it.

OVERALL: EPX has and incredibly consistent has alot of hook more than most will need and enough hitting power to stop freight train in its tracks. I never really had to worry about over throwing the ball it would just hook harder when it turned toward the pocket Only thing I had to watch was throwing to slow then I would pick up the 7-pin with a full rack HOLY HOOK! I have never had a better oil ball I can always count on it to get the job done I can't wait until they do another one of these epoxy balls this thing rocks the house

I wish I would have known about this ballreview site before I bought this ball late last year.  I have been a Columbia fan most of my bowling career and this ball has incouraged me to start looking at other Ball Manufacturers. This ball is too "high maintenance".  It started out ok the first few games then would die out.  Soaked it in hot water to get the oil out and tried again.  It rolled ok the first few frames but then died out again.  No technical terms or drilling info here, just that this ball was a waste of money and after only less than 10 games, it sits in my garage.
