Scott,
If it's of any worth,
The One7Plus cover was in use in AMF balls before the Columbia move to Ebonite. Plus long before this event, during the hubbub about the absorptive qualities of the Ebonite One series of balls, I distinctly recall a Columbia rep posting here on ballreviews.com that Columbia's newer reactive resin coverstocks (post Super-Flex) were all at least absorptive as the One series' coverstocks, and in many cases, more so. Columbia just chose not to make a big deal of it.
For my money, I think they recognized that many people might think that more absorptive covers were not always a good thing.
