TaylorMade Golf's RSi irons are long. Like a club longer than any iron set we've seen. However, for as well as the clubs (the RSi2 irons are in our gamer bag) perform, they don't quite look like a players' iron. They're a smidge thick on the top line and just don't feel quite like an executioner's blade, more like a really pretty sledgehammer.
So, TaylorMade wanted to offer a new iron for a better player that incorporated the technologies which make the RSi irons so long with the look and feel expected. They came up with the PSi irons.
PSi irons boast similar features to the RSi irons: face slots on the toe and heel from the mid-irons on to flex on mishits for more forgiveness, as well the speed pocket, now cut through into the undercut, for better energy transfer at impact. However, this look now comes in a tighter package, with a face less than 2 mm thick, carrying a thinner topline.
Engineers also went to work on improving feel and sound, developing what they call a Dynamic Feel System. The DFS is a multi-piece affixed in the club's cavity aimed at reducing face vibration at impact. The long irons feature tungsten weighting for improving quality of impact, while the 8-iron through sand wedge are forged clubheads for improved feel on the scoring shots.

The PSi iron line features faces at less than two millimeters thick, but supports that with a multi-piece cavity badge aimed at controlling vibration across the face. The 360-degree undercut improves consistency of distance by offering more uniformly unsupported square inchage on the face.
There's also a PSi Tour model, which is a fully forged set using 1025 Carbon steel. The heads are smaller for better workability, but still feature the face slots and Speed Pocket. The topline is smaller and there's minimal offset.
The PSi will be in stores Nov. 6 (MSPR: $1,100), while the PSi Tour will be available Dec. 20 ($1,300).
