Bowling balls and drilling tech has FAR outstripped any minor regulations change in RG or differential.
Limiting the low RG to 2.46 only changes it .03, which, when given the added strength of some of the assymetric cores, is almost totally negligable.
I think that if they REALLY want to have an impact, they should make some serious, SIGNIFICANT, changes to both bowling balls AND pins, as well as regulate the playing conditions under stricter, more demanding conditions.
Until they make some SIGNIFICANT changes, they aren't really all that serious about changing/improving things, only trying to please both sides by making a TOKEN change in some very MINOR aspect.
