TaylorMade Qi Individual IronQi Individual Iron Features & Benefits:Straight Distance - The majority of game improvement irons are designed in a way that exaggerates the right miss (left miss for left-handed players). The Qi Iron features TaylorMades patented face technology designed to control face flexibility and eliminate "cut" spin for straighter shots through the whole set.Individual Head Optimization - Each head has been designed to deliver specific performance for that individual iron. Starting with a foundation of maximum distance and forgiveness, the face design is tailored to deliver the launch and spin needed for straight, consistent shots with each iron.FLTD CG - The FLTD CG strategically positions the center of gravity (CG) lowest in the long irons and progressively shifts it higher throughout the set. The design produces better launch and playability in long irons with precision and control in the scoring clubs.Consistent Performance - The Qi Iron shaping has been designed for consistent contact and a larger sweet spot. The increased blade length improves forgiveness while the redefined leading-edge geometry is designed to give players a consistent strike for higher launch.
