In the 2008/2009 catalog the Solid Strike is listed under the Box finish Ball Reaction Comparison chart as being designed for Medium to Heavy Oil, in the 2009/2010 catalog the Solid Strike is described as being designed for Light to Medium oil. Did they change the coverstock for 2009/2010/ Or what? Does anyone have any knowledge on why this balls category and/or characteristics being re-classified? Thanks, Ken
