The only reason some of the professional carry more than 2 wedges ( PW/SW) is because the modern loft had super charged and the PW has the same loft as the old 9 iron loft.
Professionals don’t care about which tool goes into their tool box and they certainly don’t “show and tell”, since everyone get their bag from the sponsors.
We see lots of them carry 3 wedges simply because the proper gaping is needed; not because showing off to the guys peeking into their bags and taking photos to post on the internet.
On the other hands, I start to see many of the weekend warriors carrying 4 wedges, while they couldn’t even handle their PW and GP but they like to carry extra wedges for whatever the reason.
Same as those who could not even carry their tee shots 230 yards started to tell people “drive for show and putt for dough”… laughable ?
