Tommyboy,
You are a little off.
Columbia purchased Track in the early 90s. Phil Cardinale was the President of Track during the time the Critical Mass, Code Red Critical Mass, Cuda, and so on came out. Those balls had the ceramicore technology that he created. There is a 16# Nuke on ebay, brand new right now with a picture of the box showing the label. You can clearly see this is a Columbia pour in 1993 for Track. Phil was eventually pushed out the door and replaced by Del Warren.
Phil bought the rights to DynoThane and agreed with Storm for Storm to pour DynoThane balls. Late 2005 or 2006 Phil agreed to come back to Columbia and DynoThane production switched from Storm to Columbia.
At one point in 2005 or 2006, Columbia owned and poured Columbia, Track, and DynoThane. Columbia also poured for AMF and Lane 1 and some lower end Storm balls...so the factory was pumping out quite the amount of product.
AMF has never been bought out. AMF license companies to pour bowling balls under the AMF label. In the mid 90s, Ebonite poured the XS, Whip, and other AMF products. AMF switched to Columbia poured balls and featured the Nighthawk and Angle Evolution lines in the late 90's and early 2000's. AMF continues to license under the 900 Global umbrella, but 900 Global does not own AMF.
The EPX was the last nail in the coffin. Storm was gathering market share, Ebo was on the rise, and Columbia had iffy new ball after iffy new ball. They were solid performers but nothing that went WOW. The EPX had production issues that I know of that some others probably do not know. Essentially, the ball needed short pins and the first batches all came out with long pins. This made the ball have drills that were not intended for the ball, plus the cracking issue. The cracking issue was eventually fixed and short pins came out in later batches in higher quanitites, but the ball was already rolling downhill at that point.
I still gather older AMF/Columbia/Track/MoRich equipment because they roll so well for me. Cover/core combos just were perfect for my style. I think it has a lot to do with the covers because I can use MoRich poured Columbia balls but close to the same cores in Brunswick covers match me horribly.
WOWZERS
