My house pattern
40 feet on ProAnvil Synthetics
http://www.pba.com/resources/oilpatterns/laneconditions.asp?ID=15

Me
Strongly Speed Dominant Tweener (righty)
(throwing balls through the breakpoint is not uncommon for me)

Ball
Gross -- 15lb 3ozs
Pin to CG dist. -- 3"
Starting top weight -- 2.5ozs

Drill Pattern
From Columbia's drill sheet I chose the "Strong" pattern for my profile (SSD).
Stacked leverage -- 3 3/8" x 3 3/8"
Weight hole below my PAP on the VAL (5" from the pin)
1/2oz positive ending side weight

Results
First off, I need to say that this ball is an absolute BEAST!  No other way to put it (but I'll try).  I have never seen a ball cover so many boards on our pattern.  This ball starts rolling as soon as you put it on the lane and does not quit.  It pounds the pins into dust because somehow it stores energy.  I'm guessing it's the med-high RG core.  Great core/cover matchup by the way Columbia.

I cannot throw this bad boy through the breakpoint.  It's impossible.  The reaction shape is a very strong arc.  There is an out of bounds from the 5 board to the gutter and this ball ignores it.  I probably sent half of a dozen out to around the 2 board and the ball came screaming back.  This ball will make people think you have a ton of hand.  My EPX T1 is nothing short of a blast to bowl with as it is so much fun watching it bounce back from everywhere on the lane.  It even holds the line on tugged shots better than expected.  I used it for all three games and only had to make minimal adjustments.  My last game was actually my best (8 strikes) as I got used to such an aggressive piece.

Anyone who has said that this ball will not hook is either using it on dry lanes or they did not follow Columbia's instructions and decided to drill it tame.  I'll be honest, I haven't bought a Columbia ball in almost 7 years, but this will definitely not be my last.

CI - I think I will have to try the Action and Action Packed next.  I also want to try the U-Turn Particle Pearl.  Do you have any idea of where that would fit in your arsenal (in your signature)?

*Update*
Second Night Out w/ EPX T1:

Ball seems even stronger than the first night.  Shot 688 and could have been much higher if I had just moved a couple boards more to the left with my feet.  I only missed the 1-3 pocket 3 times the entire night and that was due to operator error.  Cannot wait until I get to throw it in league again.  Do yourself a favor folks, buy one of these before they are gone.  I bought two NIB 1st quality 15# EPX's off of eBay for only $100 shipped each!  Easily the best deal I've ever come across.

I'm a skeptic turned believer.
