This is a 2023 model P7MC 4-iron. The shaft is a Diamana Thump Iron 115x. I believe it's quite rare to find the heaviest and stiffest spec in the Diamana Thump Iron series. It's a manufacturer's custom product, so it has a TaylorMade sticker. The grip is an Iomic Matsuyama model with a backline. I got it to use as a combo with a muscle-back iron set. My personal impression is that it feels a bit stiffer than DG x100 when swinging, but the ball flight seemed to be slightly higher than with DG. I'm selling it because I've replaced my iron set and no longer need it. I've used it about 100-150 balls at the driving range, and it's never been used on a course. Feel free to comment with any questions about the price. TaylorMade P7MC Diamana Thump
