@Lucas_Wiseman league and tournament level bowlers in that region have left the game . Impossible to practice. Inflation has gone overboard. Gone are the days of work, league at night (any recreation). Life out there is commute, work, sleep, and scrounge $ for living expenses.
@Ahos300 A lot of things:
top: deflection due to rolling out, too much/little surface, soaked ball/old ball carry, maybe missed right/incorrect entry angle, poor execution/missed at bottom.
bottom: no deflection, proper entry angle, fresher cover/new ball carry, luck, better shot.
