An 0211 owner and I also feel like they are fairly soft relative to other unforged irons I've hit. I think the softest I've ever personally felt was the srixon 545, but I'm not as much of a hoe as others.
This would have been my guess. I'm too poor to afford them, but every review you can find on the 3d printed cobras, gushed about the feel.
I can't wait for 3d printed clubs to become more mainstream and prices to come down.
