On the OP question, Chuck, I don't think there's much left on the market that is truly a forged iron (beat into shape from a single piece of carbon steel). If there is, it's probably got a sweet spot the size of a pimple. Giga golf Pursuit C510 and Golfworks - if they still have any TE Forged Ieft, are examples of reasonably forgiving true forged heads that I've owned. After that, you're probably looking at multi -piece, multi-material heads with "forged" pieces (frame, face, etc). @scotts33 is in the business, so he can probably add to my opinions.
Not much help, but I LOVE the feel of my old one-piece lost-wax cast stainless steel PINGs. Get the right shaft and you're $.π
