As with anything, there is a time and place when bounce is helpful and when it is not. If you are hitting off very firm turf or shallow sand, the bounce can keep the leading edge too high off the ground/sand causing a skull or extremely thin shot that goes way too far. You have to be very careful when assesing the lie of the ball. If there is not very much air under the ball, either on turf or in the sand, you want to use a club with very little bounce. How do we know if there is air under the ball in the bunker? When we dig our feet in the sand, we will feel how much sand we are dealing with. The more you sink the more air under the ball.
Nowadays, most good sand wedges will say how much bounce they have. If your wedge is a little older or less expensive it may not say on there. When you look at the bottom of the wedge at eye level, you’ll get an idea of what you are dealing with.
How do you know how much is right for you? Well, it depends. I’ll go into that in another blog.
