The purpose of bounce in wedges is to prevent the leading edge from digging excessively into the turf, helping you make better contact. But before we can decide which bounce is best for you, we need to identify three important factors: one about the wedge, and two about your game.
PING has shown that two wedges can have the same actual bounce, but very
different “effective (real-world) bounce” because of varying sole
widths. In their example shown here, both wedges have an actual bounce
of 13°, but because of the difference in sole width, there’s a 4°
difference in effective bounce. This is because sole width affects how
wedges interact with the turf.
This ties neatly into the second important factor for us to consider; your swing plane.
Golfers with a shallow attack angle (shown left) are probably better off
with a thinner sole and less effective bounce while those with a
steeper attack angle (shown right) will benefit from a wider sole with
more effective bounce. There’s only one way to know for sure which
applies to you, and that’s to get your wedge swing assessed.
However,
there’s a third factor to consider before we can make a final decision
on your best fit; the conditions you most often play in.
If you often play in mostly wet conditions, you’ll need a bounce that reduces your risk of digging excessively into the turf. Or, if it’s mostly dry, your bounce should allow you to consistently make solid, glancing strikes without thinning your shots.
