The Importance of Impact Location
Another important factor in determining launch angle and backspin is impact location: the exact point on the clubface that makes contact with the ball. In fact, the variability in launch angle and backspin caused by various impact locations is enormous. Impact location has a much more dramatic affect on launch angle and backspin with a TaylorMade Burner 2.0 Irons driver than loft alone. And since no one hits the ball in the same place on the clubface every time—not even Tour Professionals and certainly not average golfers—we must account for the effects of impact location when talking about launch angle and backspin.
For the purposes of this article TaylorMade R9 Irons we're only talking about varying impact locations in the vertical plane, from top-to-bottom on the clubface.
Woods and hybrids, unlike irons, do not have flat clubfaces. They have curved clubfaces. The curvature is called "roll". Because TaylorMade R11 Driver the clubface on woods is not flat, the club doesn't have the same loft on all points of the clubface. For example, a driver will have more loft at the top of the club head and less loft at the bottom. The loft you read stamped on the bottom of a given driver is the loft measured in the center of the clubface. Hitting the ball above the center of the club face will result in a higher launch angle than if you had hit the ball in the middle TaylorMade Burner SuperFast 2.0 Driver of the club face. The higher you hit it on the clubface, the bigger the discrepancy in launch angle when compared to a center impact. Hitting below the center of the clubface will have the opposite effect: the ball will launch lower than if you'd hit it in the center of the club face. And it's not just the launch angle that's affected.
Titleist 712 AP1 Irons Back spin also varies greatly depending on impact location. Relative to impact location, backspin is inversely proportional to launch angle (caused by gear-effect). This means as launch angle goes up, backspin goes down and vice versa. So if you hit a shot high on the clubface with a driver you can expect the ball to Titleist 712 MB Irons launch higher with less backspin than if you'd hit the ball in the center of the club face. Again, the opposite is true for hitting the ball low on the clubface: the ball will launch lower and have more backspin than if it Titleist 712 AP2 Irons had been hit in the center of the clubface.
