Modern irons and wedges are made with different weight distributions (cavity back, muscle back, etc.) that determine the degree of forgiveness. Choosing the right clubhead according to your skill level can significantly help with consistency and confidence in your shots.

Stiffness (Flex) and the shaft material (steel, graphite, or their combination) are reflected in the feel during the swing, clubhead speed, and shot control. Every player has a specific swing tempo and personal preferences that need to be taken into account.

Shaft length affects your stance and comfort during the swing. A shaft that is too long or too short leads to compromises in technique and thus to inconsistent shots.

Lie angle (the angle between the shaft and the ground) then influences the direction and accuracy of shots. The correct lie helps to hit the ball optimally in the center of the clubface, minimizing side spin of the ball.

The distances covered by the clubs are largely determined by the loft. During fitting, attention is paid to smooth transitions between individual irons and wedges (so-called gapping) to avoid unwanted distance gaps.

For wedges, the correctly set loft is key for various playing situations – whether it's longer approach shots or short shots around the green.

Especially with wedges (pitching wedge, gap wedge, sand wedge, and lob wedge), bounce (the angle between the ground and the leading edge) and the shape of the sole (grind) are very important.

These elements affect how easily the club passes through the surface or how it can glide over the grass or sand in a bunker.
