Simply put more loft is more forgiving (You don’t slice or hook you wedges). So yes the 3-metal will curve less, all things being equal. But the answer lies is speed and distance. If you carry your driver say 250 yards (100 MPH CLUB-HEAD SPEED) I absolutely recommend using a 3 metal for tight driving holes or when you are struggling with accuracy on the driver. But if 200 yards is your max carry, you do not have the luxury of backing off to a 3-metal. It’s likely the driver will have to be used on every hole.
