I think it's a myth; their advertising states "for serious golfers". It doesn't say great golfers. I am far from a great golfer, in fact I tend to suck half the time but I use a 907D2 (10.5*, YS6 stiff, 44.5") and love it.
I have also hit the G10, Big Bertha, that SuperQuad thing, 983K, Burner, Tour Burner. I never thought that any of those clubs were materially better. I don't care about distance as much as I do about the dispersion.
