Jes,
I think so....I have often replayed the conversation that must have taken place with Old Tom and someone regarding the length of holes......maybe they just happened because of how they laid out the originals, but somewhere, they must have had the philosophical discussion on what might be best.
As mentioned, the two shotter creates strategy efficiently.
Who thought that a one shotter or three shotter made any difference, and why? I really think it was just variety, or a need to have them because of how courses had to be laid out without signifigant earthmoving. Better a three shotter than spending any real money back in those days, eh?
Or, did someone have a good reason for other hole types than the par 4? Alternatively, were there other hole types (par 2, 6, 7, 8's or 9's?) that eventually went away as too boring, under the thought that 4 was best and 3's and 5's were close enough to leave around?
