Question: What do RG and differential mean in bowling ball cores?
A: RG (Radius of Gyration) measures how quickly the ball wants to start rolling. Lower RG balls roll earlier (good on dry lanes), while higher RG balls skid longer before hooking (better on heavy oil). Differential measures how much the ball flares. Higher differential creates more hook potential and a stronger backend reaction.
