Launch Angle and Backspin
Today, most golfers are familiar with terms such as &quot;launch angle&quot; and &quot;backspin&quot;—especially as they relate to hitting a driver. These terms are mentioned often during golf telecasts and covered regularly in golf magazines. The majority of retail Titleist 712 MB Irons atgolf shops and pro shops now have launch monitors capable of measuring these and many other parameters. Launch monitors are routinely used during club fitting sessions. For the record, launch angle is defined as the angle the ball leaves the clubface relative to horizontal and is measured in degrees. Backspin is the rate the ball spins backward around its rotational axis and is measured in revolutions per minute (rpm). Optimizing these two parameters, along with ball speed, allows you toTitleist 712 AP2 Ironsachieve your maximum driver distance. Optimum launch angle and backspin rate vary depending on ball speed. However, a launch angle of 10°-14° and a backspin rate of 2200-2600 rpm can be considered in the optimum range.

So, what are the critical Titleist 910 D3 Driverfactors contributing to the optimization of launch angle and backspin? Obviously the loft of the club plays a crucial role and is vital to determine when being fit for a driver. As a point of reference, a 1° change in loft will result in Mizuno MP-59 Irons a change of 1° in launch angle and 300 rpm of backspin, assuming a center clubface impact. That means if you move from a 9° driver to a 10° driver, and hit a shot with each club in the center of the clubface, you can expect the 10° driver to launch a degree higher and the backspin rate to have an increase of 300 rpm. This 1° difference in launch angle and 300 rpm difference in Mizuno MP-69 Irons backspin is enough to cause a 5-6 yard net difference in distance. And I don't know anyone who would turn down an additional 5-6 yards off the tee.
