I bought new (used) irons. I had picked up a 3 iron and loved it, so I decided to go all in for 3-PW. Much smaller face than the XRs I have been playing. Weighted in the cavity. Had never met the 3 iron before and was immediately hitting 190+ with some shaping on TrackMan. Repeatedly. Never shanked. Dead on the sweet spot. The feel is great. You can feel the compression. Callaway X Forged CB. Got them from Callaway Pre-Owned and had them do my voodoo: Regular shaft, plus 1.5 inches length, 2 up lie, mid-size grips, 4 wraps.
I thought a smaller clubface would be harder to hit, but it forces you on the ball. There is no more club than ball, lol.
