When it comes to their wedges, tour professionals value consistently high spin rates as much, if not more, than any other trait. This can prove difficult in wet conditions, where even the slightest amount of morning dew can create a barrier between the face and the ball, drastically reducing friction and spin. TaylorMade engineered theMG4with all-new Spin Tread grooves to eliminate this issue. Spin Tread consists of deep laser-etched channels between the grooves that funnel water away upon impact, ensuring direct contact with the ball. Combined with TaylorMade's Raw Face and Raised Micro-Ribs, the MG4 produces immense levels of spin with virtually no dropoff in wet conditions.
