If you use an approach or gap wedge, do you prefer it to be more like your highest lofted iron or your lowest lofted wedge? What did you consider when deciding between the two?
Maybe matching it with your irons is better if you tend to use it more for full swings? Maybe matching it with your wedges gives you more spin and allows for more creativity around the greens?
Possible myth: I’ve heard that one of the reasons that iron sets tend to include an approach wedge now is that they’ve gone so strong in their lofts (“gain 10 yards just by buying our clubs!”) that the approach wedge is closer in loft to an older pitching wedge.
