what are the differences in the gb coverstocks that ebonite uses on
their mid and high end balls? do they tweak them to make them more
or less aggressive like brunswick does or is it the same basic
coverstock? is the gb coverstock like storm's reactor coverstock
where the cover gives any ball using it the potential to be aggressive
because the cover dominates the weight block? i.e., if ebonite put a
gb coverstock on a tornado it would no longer be good for drier lanes.
