1. Is there a standard weight that comes with the 913D2?
2. What ball flight changes are expected with increasing or decreasing the weight?
The weight will depend on what shaft, length, and grip are ordered with the club. Generally, the standard weight will be the 9g weight to bring the club to a standard swing weight of D3-D4. The bezel weights will have NO direct influence on the ball flight or spin, just swing weight.
