This isn't really as much of a question as it is an observation. I have an oil extractor,(Innovative, two ball). Anyway, I drilled a big hooking ball for a friend of mine in December. He has 42 games on the ball, plus pre-league warmup, so maybe 50 games. I put the ball in the extractor not expecting much, and it took over 4 hours to bleed out all the oil. That is the quickest oil soaking I have ever seen from a ball. I was amazed that in that short a period of time it soaked up that much oil. I know that he doesn't bowl in any other league, or practice at all, so the game count is spot on. I have some equipment that has over 100 games, that will barely raise a sweat in the extractor. I guess those dull hooking beasts get that way partly via oil absorbency. The house we bowl at uses "Ice" as well, which should limit the oil absorbency to the best of my knowledge. He also usually plays outside of the track, so he isn't really keeping it "in the oil" as much as some bowlers might ... if that matters.
