2. 770CFE (-6 yds)
3. 560MC (-6.5 yds)
4. 979SS (-8 yds)
5. 752TC (-9 yds)
6. 555C (-11 yds)
7. 555M (-14 yds)
Ranking of Shot Distance (based on the 5 iron, from longest to shortest with robot hit testing at 75mph with impact directly in line with the CG)

2. 770CFE (185 yds)
3. 979SS (180 yds)
4. 752TC (179 yds)
5. 560MC (179 yds)
6. 555C (177 yds)
7. 555M (176 yds)
NOTE: Testing was performed at the 6,500 feet elevation of Durango, CO. For sea level conversion, multiply data by 0.93)
