Just figure out which dot color you are with Pings fitting system and then pick up a used pair of ping irons on eBay with that dot color. Those irons seem to always be solid no matter how old they are and they’re pretty close to fitted for you then without going through actually having clubs fitted.
Drivers, woods and wedges always seem to be easy to find 1-2 years used for top of the line stuff because so many golfers upgrade yearly on those.
Putter is worth dropping $250+ on getting one you roll well and have confidence in.
