I have not measured any of the sub70 irons so nothing to compare from and actual measurement standpoint. If you’re trying to match the lofts, then what jbhoover stated would be the ones to compare. Both the ones he listed are Ultra Game Improvement designs. From an overall profile standpoint, you might look at the TS3.5. A more classic profile but one that might have some similar characteristics with regards to construction (although I don’t really know what is in the gi22), you might look at the TS1-IM.
Confident any of ours will perform at the highest level.
