Mike, I have no doubt that Flynn, Tillinghast and others were not a fan of template holes. From a business standpoint, these guys were probably in competition with Raynor on many projects. It is only stands to reason that they would develop a professional rivalry, and their design style, and sales pitch, would have to be quite different. I know for a fact that Tilly, Ross and Styles & Van Kleek were asked to submit "propositions" for Hackensack, but Banks won the job. I would have love to have the transcripts of each of those guys making their pitch, which almost certainly would have included their comments on the other styles...
I can't prove this, but I think they all took a bit of pleasure erasing much of their rivals work when they got their hands on one of the other's courses. That is evident at Shinnecock with Flynn, and Tillinghast at many MacRaynors when he consulted for the PGA.
