Your post seems to contradict itself. Do you mean "Old" PhDs should not be consulted, but "Young" ones are OK? And how broad based are your experiences with "inflexible" PhDs? I'm sure many on this board have contrary examples, including myself, though in my case the PhD might not be considered a "hard" scientist. His specialty was Geography and Anthropology, though he was very scientific minded.
