NOT the Total Hook in a box that everybody seems to think it is.It hooks alot but there are other balls that cover more boards or an equal amount.The difference with the EPX is HOW and WHEN it hooks and the way it continues through the slick hang spots in the backends.This ball is more controllable than any reactive.It is very forgiving missing the target inside or out.It is like an old style urethane on steroids.No surprises.It hooks in the front and mids and just keeps on arcing like a freight train.No Snapping. No Skidding.See bowling this month magazine reviews.Pretty accurate review in my opinion.I used it for 8 games today  on brunswick anvilanes which have hang spots in the backends.Today medium oil.290 second game.This ball is not a low rg that will rev up by itself.I had to hit it hard to rev it up and used med -high speed.I never had to move my feet left of 22 board the entire 8 games.Just keep in the oil and hit the pocket all day.Great ball. Definitely something different.Dont listen to the hype that it hooks too much.Drill it strong.Weak drillings probably wont work.

AFTER further use I have noticed that this ball does not like carrydown.The TRACK gp2 handles the carrydown much better.The gp2 is drilled exactly the same,and I was doing everything the same(feet and target.The Gp2 blew it away.The EPX is not rolling out.It never does.It is actually getting stopped by oil in the backends.The EpX is better than anything I have thrown on long oil with clean backends because it does not snap on backend but has powerful arc that does not quit and hooks in the early and midlane.But other than that conditon there are better choices. The lanes were  Brunswick avilanes.

The ball getting worse and worse with more use.Leaving 5 pins and 5-7 splits.Poor carry.Move left into more oil and ball will never come back to headpin(except if backends are bone dry)Move right and hit pocket with poor carry.The ball acts like a regular urethane at times. It absolutely HATES CARRYDOWN.It actually hooks and hits better as the lanes dry up a little.Then you can move left and it hooks big.Very strange ball.If you use only columbia,get an ALTER EGO.1000 times a better ball.

This ball appears to be very release sensitive.  When I first tried it, the lanes were fresh and I used my normal delivery and the ball left a ton of 10 pins.  Loose it just a bit off your hand and you would leave weak 5 pins.  I was playing 20 to 10.  When I moved out on the lanes, 10 to 7, the ball acted a lot better.

The second time I used it, I was playing 20 to 10 again but gave it more hand.  The ball was a truck and carried everything.  The lanes were oiled the night before and no one used them.  Based on this, I would say that strokers should play up the boards and the bigger hand folks can just swing it and watch it come back.

Bottom line, a bit too sensitive for me, will probably end up on the for sale rack.  Will use it one more time tonight, this time in league, and that will determine where it ends up.

Used this ball for two days now, and I am more than satisfied. I bowled on wood, and synthetics. I found this ball to be more versatile than most people think.I played them all across the lanes, deep inside, slow hook, track shot, and even outside, up the boards. True,I feel it is a little speed sensitive,but with tweaking the speed , and the release, I was able to play the whole lane, and strike at will. I think Columbia has a winner here, and although most people feel it only effective on a long oil pattern, I beg to differ. I found it quite versatile on various patterns, and I am very impressed.Drill it strong, you will not be dissappointed!!

span: 2 thumb holes (one for axis tilt) and about 4 inches from the fings.
revs: about 17
ball speed: 69 (lol) 19
pap: it's as round as they come
cg: 5 mm's from core dynamics
core: double diamond

ok, do I was skeptical at first, but now I absolutely hate this ball. I was bowling on these dry lanes and busted out my smash/r but it hooked 2 much. Then I took out my epx and it is a roll out machione. I could not get that orb 2 move much so I pooped on it. it really increased midlane rxn and shiz. so i c.u.m.'d in the 2nd thumb hole and it made the coverstock more adaptable to the condition. I like it now.

This ball is not one that I will keep.  It is going back because of a crack below the thumb hole.  Was ok for a few frames, but died out quick.  Seems like the core/wb is seperating from the coverstock, sounds very empty when hitting the rack.
Everyone mfg's a dud now and then, but for the price......ouch!

Believe the hype, this ball is what it claims to be.  The ball won't roll itself down the lane and string 12 in a row like some people are apparently hoping it will do, but it does what Columbia claims, it has a very aggressive midlane along with a merciless backend.  There are balls that hook as much as this one does, (Goliath, Rule GP2, etc.), but those balls are fairly condition specific, if there isn't enough oil for them you may be able to move deep enough in, but they burn up and hit very flat.  When playing very deep with the EPX-T1 you may notice a slight loss of carry, but it maintains it's roll very well, and still drives through the pins with a lot of energy and force, and if there is a lot of oil, you can play straight, and get the entry angle you're looking for.  This is a very good release in my opinion, and I see a lot of epoxy releases with different cores in the future.  Hopefully the coverstock will be as durable as Columbia claims it should be, if it is, this is a real winner.

Came in at 2 inch pin and 3 oz top, oh yeah and dull light purple slightly tacky.  Drilled it like my other symmetric equipment, pin inbetween and below the fingers with the cg kicked.  Bowled with it on a fresh 38 foot mediumish oil pattern ball, gets into a roll but will not break early and it does have a large amount of arcing backend.  It is the most continuous arching ball I have every thrown, I was practically flushing out the 8 pin every shot.  Bowled with it for 3 games and it did develop and oil ring around my track which is dark purple and slightly different texture.  The ball did not change its reaction much in these three games.  

I then sort of followed the instructions and cleaned it with track clean n smooth, not the clean n dull that it recommends.  The ball became kind of shiny, slippery like the oil ring texture, and very dark purple.  Didn't like that look and put neo tac hook-it on it, dulled it down a little but still felt that same texture.  Then I decided to hit it with something that guarantees it to be clean, ACETONE used it and cleared up all the slippery texture and lightened it up a little too. I know its illegal, but I don't care.

Threw it again this morning at another house about 10 games with it, on medium oil and a significant amount of carry down, the ball didn't really hook that much, got into a roll but shut down on the back.  This is not you're ultimate ball, hook in a box, hook on everything type of ball, you need cleaner backends to really see the greatness of this ball.  It rolls great and is very smooth and predictable, it is worth the money!

I then gave it to my pro shop to clean it with clean n dull, the recommended cleaner, and it made the same dark purple but did not produce that shiny texture that clean n smooth does.  The ball driller also was using a red shop rag to clean it with and the redness bled into the ball!  

This ball is something new and will/is changing the game of bowling.  It is very predictable and does not hook early like high load particle nor skid flip like the reactive resins.  

I have heard that this is the least hooking of the first made epoxys.

First of all, I have not drilled one of these for myself.  I have drilled two of these for customers.

1st customer:  Med-High tracker
2nd customer Full Rolller

Went with the most aggressive layoiuts possible for each bowler.  First of all, there are balls on the market that will hook more than the EPX on most conditions.  But, I found that the EPX will hook when other balls will not.  The EPX gives the same look on Med-Heavy to very Oily pattens for these bowlers.  

Bottom Line:
     If you are bowling on a house shot and want more hook, go with a high flaring high-load particle or solis reactive at about 500-grit.  If you want a ball that will give you consistent hook without over-reacting on the backend, I suggest that you take a look at the EPX.

I've found that the RESET button is the easiest way to knock down ten pins.

Call this a first impression post. Drilled the ball with pin at 4" and cg kicked out towards PAP to put the mass in line with my VAL. I had to add a small weight hole on my PAP. Ball has 2 1/4" pin and 2 1/2" oz of top weight to start.

For some reason our backends were not moving last week, so since I had drilled up my EPX just before league I figured why not. I had already tried both of my Big Bully's with no consistent reaction. Well after 7 frames I bagged the EPX, I could not keep it on the right side of the headpin. The two times I got it over there I had one strike and a heck of a mix to end up with a 10. I have never owned anything that hooks like this did on first impression. I am hoping to find oil soon and if I can get off this Friday, I will. I will be in Arkansas and shooting on 44 foot of PBA pattern. Now that will be a huge test for the ball.

Just to follow up. The EPX did not hook that much more on the 44 foot pattern this weekend than my other balls. However, they used a heavier version that had a huge out of bounds and the lanes played best for me going up the boards. So, no swing was needed or used. I never tried it during qualifying, only practice. I did see a lot of guys using theirs though with mixed results.

I debated about even trying this ball for a couple of weeks, but my curiosity got the best of me.  The ball is set up along the lines Columbia recommended with a leverage pin and strong cg position requiring a balance hole below my PAP.  I have now tried the EPX in 3 different anvil lane houses of varying ages, and on both fresh and broken down conditions.

My first outing was on 7 year old anvil lane with a long oil 10 to 10.  The oil was prodigy.  I tried to line up a bit inside the oil line to see how strong it would be.  I got a lot of skate out and was unable to get the ball back to the hole until I moved well right into the dry area.  The ball rolled up strong and did not over react in the dry, but carry was spotty.  The reaction on this condition reminded me a lot of my old Blue Hammer.

I next bowled the same house after league where the shot had moved into about 17 at the arrows.  This time I got a much better reaction plyaing against the inside oil out to the track.  Carry was better, although both my Ultimate Inferno and Absolute Inferno were stronger and had more continutation.  

Next effort was on a very old anvil lane house with a defined track area at 3rd arrow.  I was able to move in to 15 on fresh oil and scored extremely well.  My AI still rolled stronger with a similar breakpoint, but more continuation.  

The last house I tried was a new pro anvil lane center on a fresh condition.  Again as in the first house I was not able to get much of a back end reaction and carry was spotty.  All of my resin equipment, including my Freak a Zoid, opened up the lane and carried better than the EPX.

Despite my less than earth shaking results, I would not call the EPX a bad ball.  In my hand it definitely needs either a booming back end or some dry boards to the right, but I think heavier handed young guys might be able to exploit the ball a lot more than I could.  In that respect it reminds me a lot of my old urethane balls of the late 90's.  This ball does not like carrydown.  

In summary, I have often said that the modern resin balls remind me of my old yellow dot on steroids.  If that is indeed a good analogy, then the EPX reminds me of my old Blue Hammer on multiple vitamims.

Long time, first time in the columbia world.. I may sound like others when I made the decision to drill up this ball compared to a Track Delta 1.

Specs on the Ball - 15 pounds 4oz with 3 1/2 top with a 2 inch pin.

Reason on drilling the ball was to have something stronger in my bag for med. to heavy lane conditions and my Rpi regional in Austin with the 42 feet pattern.

My Profile has my info on how I throw the ball.

Layout on the ball is a 3 3/8 by 3 3/8 with a weight hole .5 inch above my PAP.
Ball is left at factory finish.
First impressions - Bowling at the famed Astro Bowl( Old wood with a Burned Track at 10)  .. I stood 34 with my feet and hit 23 with the ball rolling to 13 at 40 feet and making a sharp recovery to the pocket. After about 12 - 15 shots hitting the pocket, I moved my feet to the right at tried to stand 23 and hit 17. As I suspected as did my ball driller, the ball pinged a 10 pin and We ( mostly the ball driller ) said it was burning up.  

Overall - it's too early to tell but I will return from a tourney this weekend and find out what this ball does on Syn. lanes in Austin this weekend on Pattern 4 which is 42 feet.

P.s. - Don't be afraid to drill this ball strong..... It meant for Heavy oil and remember what is heavy for me coulfn't be heavy for you.

Drilled - 5x4, pin below bridge, low small Xhole
Coverstock - out of box

Biggest benefits: strong strong roll. much better hit than any strong particle I've ever thrown. But the best characteristic Ive seen is when it encounters friction... When most particles encounter early friction in Mids/heads, they tend to rev hard/roll out, burn up and hit badly.

the EPX-T1 is completely different. It reads the early friction, doesnt hook instantly, continues to roll harder thru the friction. Its continuation is its best attribute, then the hit. Doesnt rip racks like a strong reactive but definitely hits better than any other Strong Particle. arc arc arc.

Im not afraid of this ball burning up so I want to drill another one even stronger for really long difficult patterns. Its a definite breakthru and worth a try. Oh, and I leave mine in the car and have yet to see any type of crack.
