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

The stiffness (Flex) and the shaft material (steel, graphite, or their combination) affect the feel during the swing, clubhead speed, and shot control. Every player has a specific swing tempo and personal preferences that need to be considered.

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 inconsistent shots.

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

The distances covered by the clubs are largely determined by the loft. During fitting, smooth transitions between the irons and wedges (known as gapping) are ensured to avoid unwanted distance gaps.

For wedges, the correct loft setting 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.
