My oldest club in the bag is a ram investor II 4 wood from the 70s, I also have a ram tour grind tom Watson gap wedge from the early 90s. My mx-23s are ten years old, but I don't have any plans of changing them out any time soon.
I have played a 64 for the past 3 years, and it is great out of the bunker and on close/tight shots around the greens (I never take a full swing with it). After my set P at 46, my wedges are 50, 58, 64. Big gaps, but I'm comfortable with them.
You could hit the nikes to verify, but I'd say stick with your original plan on the pings. You have hit them, and liked them, and you can have them fit/made to your specs. Good luck with your decision!
I'd say driver, 4 wood and then hybrid or 7. Loft wise, I have a 9* that I like, but it seems like the trend is toward higher loft, so 10.5 May be the way to go. Try them out if you can.
Too bad Tour Edge doesn't pay their players, you'd be in line for a full bag deal.
