The Mizuno T-11 wedge is basically the Mizuno T-10 wedge that has been updated with new grooves to conform to the 2010 condition of competition regulations. These rules don’t apply to non-elite amateurs until 2024, but that does not mean that you should forget about this wedge until then. As well as making the grooves conforming, Mizuno have added some roughness to the face of the T-11 wedge between the grooves using CNC milled score-lines to add some extra grip on shorter pitches.
