I was recently at Chuck Evans he said he hits persimon 4 yds further than titanium and was going to go back to a persimon driver instead of a hot faced callaway.
Testing has shown that these so called longer drivers are in fact shorter than manufacturers want you to know.as long as you can hit the sweet spot .

Chuck Evans can probably hir ANY driver LOOOONG. He IS LONG!!!
It would be interesting to see some testing on this... WOOD vs. METALS.
