Question 3

In custom club fitting, what does 'swingweight' measure?

The perceived weight distribution that affects feel during the swing

Answer

Swingweight measures how the club's weight is distributed between the grip end and head end, affecting the perceived heaviness and feel of the club during the swing.

Question 4

Which shaft material provides the best combination of light weight and high strength for modern performance golf shafts?

Accepted Answer

Graphite (carbon fiber composite)

Answer

Graphite (carbon fiber composite) shafts offer superior strength-to-weight ratios compared to steel, enabling lighter overall club weight that can increase swing speed.

Question 5

What is the primary function of grooves on a golf club face?
