Devil's advocate would say that of course Shot Scope data would show Driver and 3W have the same FW%, a 3W is 1/3 the size of a driver and therefore much harder to hit accurately.
I agree the 2nd driver still probably wouldn't make sense from a SG perspective on a plain Jane par 4 with no trouble, but there are lots of holes where SG would say to hit 1 club less than driver to be short of a cross bunker, water hazard, etc.
On paper a smaller 3 wood should be harder to hit straight bu my strong 3 wood is much, much straighter than my driver and my 4 wood is even more accurate. Maybe it the extra backspin or maybe I’m just more confident with my 3 wood after it being a fairway finder since I was a teenager. From the 6,540 yard tees at my home course, I’ll hit less than driver off the tee on 5 of the 9 par 4’s. Anytime it’s less than 400 yards, it’s generally a 3 wood or less.
