Just wanted to update this thread since the purchase.
I wanted to move from the PX 6.5 to a TTx100, and I found a set that seemed to fit well. This set was +1/4" with Tour Issue TT x100 shafts and a new set of midsize Golf Pride New Decades. These sticks were supposedly built by the tour department (had the tour ferrule) and played by a mini tour player in AZ. Irons were in great shape and I picked them up for $265.
After a few range sessions and 2 after-work nines, I'd have to say I love these irons. The shafts feel wonderful compared to the PX, and these irons are quite a bit more forgiving than my musclebacks without constraining shot shaping too much. This set plays about a club longer for me, and the feel for a cast head is excellent. I can't flight the ball as easily as I could before, but that may come with time and I get used to the new set.
For those looking for a great value in a players cavity, these sticks are very solid.
