Introduced in 1998, the DCI 981SL irons were identical to 981 set, but modified for golfers with slower swing speeds. The 5-iron through PW featured a longer hosel and stronger lofts for increased distance. The long irons feature increased offset, a shorter hosel length, and lower CG for a higher trajectory.
The men's version was available in 2-iron (21°) through 9-iron (41°) and PW (45°) with a C9 swingweight.
The women's version was the same in C7, minus the 2-iron.
