Ken, I've tried balls with almost every coverstock on the market. Your driller is flat wrong. The soaker does last substantially longer and perform at an acceptable level longer than reactive or particle coverstocks from Columbia/Track/AMF/Morich, Ebonite/Hammer, Storm/Rotogrip and Visionary. It seems to last somewhat better, though the difference is not as clear, than Brunswick coverstocks -- which can be more easily revived than the Columbia, Ebonite and Storm family reactives (whose particles just flat go blah). It does need periodic cleaning and, in my experience, resurfacing after about 120-160 games (it begins to lose some reaction). After a resurfacing, in my experience, the performance comes back to near new (which is where you want it anyway for this coverstock) for another 140 or so, before it needs another resurface. So far (and I bowl about 30-60 games a week) I haven't seen one come to the end of its useful life.
Perhaps what your driller is referring to is "new ball" reaction. Well, the Soaker does lose that reaction after about 20-30 games. But, quite directly, the new ball reactions on the soaker are not nearly as good as the reaction once the coverstock is broken in. From my experience, the soaker has longer top level performance than almost any other coverstock -- probably any other, though some of the Brunswick coverstocks (not my favorite on performance) seem extremely durable and long-lasting if maintained properly.
