NIKE'S FITTING METHODOLOGY
1. The Nike fitter watches you hit balls with your current driver. The launch monitor records relevant info (ball speed, launch angle, spin rate, etc).
2. You hit a few shots with the Nike Str8-Fit driver.
3. The fitter makes adjustments to the clubhead (loft, face angle, lie angle). He might also switch the shaft. These tweaks are based on his observations as well as launch monitor data. This is the "intermediate fitting."
4. You continue to hit balls with various head-shaft combinations until you home in on your optimal fit.
Tom's angle of attack tends to be too steep and creates too much spin. Like a lot of amateurs, he loses it to the right on bad swings. The goal is to bring down his spin rate while helping provide a bit of draw bias.

Sean's go-to drive is a slight fade. We want him to still be able to hit that shot consistently while increasing his launch angle and carry distance and reducing his spin rate. A higher launch and less spin will get him more roll and overall distance.
