The Tour HDI Driving irons were discontinued. At this time we have no replacement for that kind of design. We do have a new hybrid that we hope to have by mid June that is replacing the KE4 Tour Hybrid. We have a new iron, the TS2, that is a players cavity that is a Super Game Improvement iron that we hope to have by the first part of June. The Muscle back, or more accurately, a non cavity back blade iron (The TS1) we hope to have by July. We also have a driver in the works that will be later in the year. All are tentative timelines, but the Hybrid and TS2 should be on schedule. No pictures yet, but will release as we get a little closer to the available date.

The TS2 preliminary MOI is 12.4474 ouin². The STi-HS is 14.1098 ouin². So the STi-HS is a little higher, but the difference is not enough to influence the performance in a major way. For irons, both are on the high side for MOI.
The TS2 will have a thinner face design, creating higher ball speeds off the face.
