The frequency of changing golf wedges depends on the conditions in which you are playing, the type of wedge you have, and your personal style of play.
Firstly, based on the condition in which you are playing, a player may need to change the end on their wedge more frequently due to the deterioration of their clubs in the moist, sandy and salty environment.
Similarly, if your distance control is inconsistent when putting with the same wedge then you may need to change the club. It may be a sign that the grooves of your wedge have worn down and need replacing.
Also, the type of wedge you are using will also dictate the frequency of changing it. Generally, a player may want to change their wedges every two to three years, however, if you are using a higher end wedge, you should be able to retain its quality longer.
Finally, your individual style of play will play a determining factor. If you’re a high handicap player and you’re finding that you’re losing accuracy and spin control when hitting the same type of wedge then you may need to change it more often. However, if you’re a better player and your wedge performance is consistent, then you may choose to keep it for longer.
Overall, the frequency of changing your golf wedges depends on the type of wedge, your approach and the environment you play in.
