If you play from tight lies and bunkers with thin sand, this could be the best wedge for you. Your wedges could be costing you A LOT of strokes. In Central and Southern Texas, also in Southern California, where I used to live, had really tight lies. I have spent a long time searching for the right grind and bounce combo on wedges. These Wilson Staff Tour Grinds might be the best, most versatile wedges I have ever used.
Wedges for firm conditions can travel to softer lies, but you CAN NOT use a soft condition wedge on firm lies without some swing dynamic changes.
