The R stands for Refined: TSR reworked TSi's aerodynamics rather than starting over, and split face technology across the range. TSR2 and TSR4 use a layered Multi-Plateau VFT face for near-constant CT across the hitting area, while TSR3 uses a Speed Ring face that concentrates peak CT in the middle.
