The 921 Forged irons are going to sell well for their segment and I have a feeling they will be real popular with THPers. I’m coming from P790 and Forged Tecs this year and the spin is clearly higher with the 921F, which has made them super consistent with distances. I’m maybe a half a club shorter (maybe a 1/4 of a club - some more data Is needed) but I’m hitting and holding way more greens. That is a trade I will trade every single day.
Forgiveness low on the face is good too - the launch is definitely lower but the distance was basically the same as well struck shots. It’s a different way to get to the same spot. Of course, sweet spot strikes feel amazing and fly so darn true. So darn true.
How much of the differing performance relative to the Forged Tecs/P790s is the head vs the shaft? It may be impossible to answer.
