The profile is a little different. It is a progressive cavity design and the lofts are stronger (28 deg. on a #6 iron vs 31 for the TE). Playability number is a little higher on the TS3, but both are considered Super Game Improvement and I don’t think you would notice any difference in stability or forgiveness. They do have similar sole widths and sole angles. The TS3 has a lower heel height and does have a little more offset in the long and mid irons. So, in short, the TS3 should look a little different to you at address, but provide the same playability and most like longer distances due to the lofts. The TS1-IM and the TS4 will have more of a blade profile, but I would call them more similar to the TS1 and MMB-17 respectively. Even that being said, I think they are noticeably different in their own right. I do think “blade” players are going to love the TS4 and TS1-IM. The TS3 I would classify as more of a progressive players cavity design.
