You'll see that the back edge of the flange is lower than the leading edge of the clubface. The more bounce, the more likely the club won't dig in the ground. That's especially helpful in getting the ball out of sand or heavy grass. But on tight lies, too much bounce makes it easier for the clubhead to literally bounce off the ground, striking the ball near its equator and sending it seemingly toward Earth's equator. Tiger Woods , for example, has six degrees of bounce on his sand and lob wedges, Vokey said.
Technique is crucial.
It all depends on what players are comfortable with. Davis Love III 's wedges have thick soles, and he chips as well as anyone. Club meets ground precisely where the ball rests on the ground. Players describe it as sliding the face of the club under the ball. Having less bounce on their wedges makes those shots easier.
