Following on from part 1 I managed to repeat my testing on a GCQuad.
The Epic Sub Zero should be lower spinning.
The Epic Sub Zero should produce a longer carry distance.
Within the limitations of my setup I tested by capturing multiple shots (not blatant mishits) with each club/config.
The clubs used were:
Taylormade M2 (9.5deg adjusted to 7.5)
Callaway Epic Sub Zero (9 deg)
The ball used was the TP5X.
Results and Analysis
Epic SZ Shot
I was impressed in part 1 but the data from GCQuad is amazing. Over the course of 15+ shots I averaged 20 yards greater carry.
It is now clear from the data, validated on 2 launch monitors the 2017 M2 doesn't suit me. The combination of slightly higher ball speed and significantly lower spin means the Epic SZ is way better in my hands. 20 yards equates to approx 0.06 strokes gained every shot which could be as much as 0.8 shots per round!
