When evaluating golf poles, you must focus on shaft material, flexibility, and head construction. For shafts, high-modulus graphite is preferred for its lightweight and vibration-dampening properties, while stainless steel (304 or 431) or carbon steel is ideal for irons requiring precision. Ensure the flex rating (Extra Stiff, Stiff, Regular, Senior, Ladies) aligns with your target market's swing speeds. Additionally, verify the loft and lie angles meet a tolerance of ±0.5 degrees to ensure professional performance standards.
