Indeed, the lane oils used today are generally slicker than they were when those balls were released . In general, there is also more (oil) volume being applied today.
I recently pulled out my old Brunswick Danger Zone (the original one) and threw it
on several different conditions. It goes very long and straight for me on today's conditions. When I first bought it (20 years) ago, it was a hook monster. Not now. Same with an original Columbia Pulse that I have not used in close to 20 years.
