I see this question asked in various places and the answer is always the same. Not to offend, but what conceivable difference does it make? As Charlest so wisely pointed out, it depends on so many factors as to be virtually incalculable. Plus, I doubt if very many of us have ever run into the condition where we would use this ball. As others have suggested, while it is not the intent of your question, I think what may be important is what is/was the biggest hooker in contrast with its contemporaries. This has relevance because of the influence it might have on the following "generation" of bowling balls. As an aside, if it's of any importance, I've seen people who can hook a target zone off the lane, so maybe it's a question of what ball in your hand is the biggest hooker.
