Question: Do Course Conditions and Swing Type Influence How Much Bounce I Need on Wedges?

Answer: Yes, course conditions and the way the golfer swings the wedges down into the ball have a bearing on how much bounce is good or bad for any golfer.

The fluffier the sand, the deeper the sand, the lighter the sand, the longer the grass in the rough, and the steeper the golfer swings the wedge down into the ball, the more bounce on the sole is required to be consistent in shotmaking.

Conversely, the more coarse the sand, the more shallow the sand, the heavier and wetter the sand, the shorter the grass in the rough, and the more level the golfer swings the wedge down into the ball, the less bounce on the sole is required to be consistent in shotmaking.

下過雨後的同樣的沙坑, 因為沙子變得比較硬, 要使用 bounce angle 比較小的, 如果這時你用 bounce angle 大的, 因為沙子硬, 壓不下去, 反而會反彈回來, 造成 top ball.

不知這樣的理解可對??
