Titleist DCI 981 SL irons. Designed for slower swing speed golfers seeking DCI solid feel and performance. Increased offset combined with a shorter hosel length and lower centre of gravity in the long irons create a high, yet boring trajectory. Longer hosel length and progressively reduced offset in the short irons produce a lower, more manageable trajectory. The DCI 981SL is designed for the slow swing speed golfer seeking DCI solid feel and performance. Cast from 431 stainless steel, the DCI 981SL features increased offset, a lower centre of gravity and a wider sole, producing a greater right to left tendency and higher overall ball flight than DCI 981. Also, stronger lofts (SL) in the 5-iron through pitching wedge provide greater distance.
