Wowzers,
I know and understand that. I guess I wasn't really asking, as much as being sarcastic. The difference with finding one of those older balls is, that the cover material on the older balls wasn't created with current oils in mind, new balls are. Bottomline, if you take a modern coverstock, and create the most potential flair by altering the core shape, you are increasing traction throughout the entire lane, something that is more beneficial to lower rev, higher speed dominate players, or bowlers bowling on true heavy volumes of oil. I haven't worked with the maps program to really see how carving a core changes ending values, I just go by past experience of knowing what layout I need to use, depending on my customer. If I max out a 0.045 diff ball, a 0.058 diff ball, and a 0.060 ball, the 0.060 ball is going to have the greatest chance of creating the most track flare and yield the highest chance of having fresh cover touching the lane to create traction. You go over that number and the scaled percentages go up consistently with the diff numbers. Basically, I think it would be easier to create an ending diff of 0.070 out of a 0.061 ball, than it would be out of a 0.055 ball. There has to be a point where all manufactures have to have a pre-drilled limit.
The point is, people act like just because you can take a ball and go over the number, that these balls should be over-looked. I'm just saying that the percentages are in the favor of a ball with a higher diff to create more traction, especially with some of the oils that have been coming out these last few years. I know personally, I need to use stronger layouts than years past, to create proper roll through the pins, especially when I see Ice oil on Pro-Anvilehang.
