⛳ Epic Golf Fitting Knowledge Center
Choosing the right equipment is key to improving your game. Use our guide to understand how club parameters affect your shots.
1. IRONS: Precision and Forgiveness
Iron selection is based on swing speed and matching shaft weight and flexibility.
A. Shaft Weight: Light or Heavy?
Shaft weight affects swing speed and club feel at impact:
-
Light shafts (50–70g): Allow for higher swing speeds; ideal for those with slower tempos or seniors.
-
Medium shafts (70–90g): A balanced choice for many players looking for a compromise between control and speed.
-
Heavy shafts (90–130g): Offer greater control and stability; ideal for players with high power and fast swings.
B. Flex (Stiffness): Matching 7 Iron Speed
Flex describes how much the shaft bends during the swing:
-
Ladies (L) & Senior (A): Ideal for speeds <70 mph. Helps to get the ball airborne.
-
Regular (R): Perfect for recreational players with an average speed of 70 – 80 mph.
-
Stiff (S) & Extra-Stiff (X): For players with high speeds of 80 – 90+ mph and an aggressive tempo.
* The above information is general. Optimal selection also depends on your individual feel and ball flight shape.
C. Choosing the clubhead
-
Players / Tour (Control): Small heads for feel and precision (T100 / T150 / P770).
-
Players Distance (Sweet Spot): Sporty look with distance technology (P790 / T200).
-
Game Improvement (Support): Large, forgiving heads (Ai300 / Launcher / Ai-Smoke HL).
2. DRIVERS: Maximum Distance
For drivers, the key is the right loft and shaft stiffness matched to higher speeds.
A. Driver Flex (Swing Speed)
-
Below 85 mph: Ladies / Senior / Light Flex. Maximum distance assistance.
-
85 – 95 mph: Regular (R) Flex. Stability for average amateur speeds.
-
95 – 110 mph: Stiff (S) Flex. For hard hitters, reduces ball dispersion.
-
Above 110 mph: Extra Stiff (X) Flex. Highest stiffness for PRO players with high clubhead speed.
B. Loft and Angle of Attack
-
12° - 13.5°: Helps keep the ball in the air with a slower swing.
-
10.5°: Standard choice for most players.
-
8° - 9°: For powerful players who want to reduce spin and lower ball flight.
C. Head Type
-
MAX: Greatest stability (e.g., Quantum MAX, Qi4D Max).
-
LS (Low Spin): Reduces spin (e.g., Quantum Triple Diamond, Qi4D LS).
-
Draw Bias (D): Helps eliminate slices (e.g., Quantum Max D).
3. WEDGES and LIE ANGLE
-
Wedges (Bounce): Choose High Bounce (10-14°) for soft courses or if you take deep divots. Choose Low Bounce (4-6°) for hard ground.
-
Lie Angle: The correct Lie Angle ensures that the clubface contacts the ground flat, eliminating the ball veering off target from the start.
