Not just for wedges
Gapping is often associated with the shorter clubs in your bag, but it's just as important to make sure you pay attention to the gaps between your longer clubs, too. Good gapping would see you have equal gaps between clubs that are no bigger than 15 yards, as displayed in the green illustration below. In contrast, bad gapping would leave you with uneven or large distances between clubs, often over 20 yards or under 10. Having equal gaps throughout your bag will mean you are much closer with your next club, so you won’t have to manufacture shorter/longer swings or hit soft/hard shots, which is where a lot of problems begin. |
