Which is most affected when changing an iron's total weight by switching from a 60 gram graphite shaft to a 110 gram steel shaft?

Switching from a 60 gram graphite shaft to a 110 gram steel shaft significantly impacts the overall weight of the club, which in turn influences the balance and tempo during the swing.

Balance refers to how evenly the weight is distributed throughout the club, which can affect how a golfer feels the club during their swing. A heavier steel shaft can lead to a different swing weight, requiring adjustments in how the golfer positions and swings the club.

Tempo relates to the rhythm and timing of the golf swing. A change in weight can lead golfers to alter their swing speed and timing. Heavier shafts may necessitate a slower, more controlled swing to maintain balance and ensure proper mechanics. This alteration in tempo is crucial for achieving consistent and effective shots.

Options discussing tension and sequence, posture and alignment, or aim and arc width involve other aspects of the golf swing but are less directly impacted by the club weight compared to balance and tempo. Thus, balance and tempo are the most affected elements when changing the shaft weight in this manner.
