JES II,
I wouldn't say "Ideal" I would say, "Intended"
If an architect designed and built a hole with a 75 yard fairway, my instincts tell me that he had good reason to do so, and that there's a correlation between that width, the architectural features, configuration of the hole and the green and surrounds.
That doesn't mean that the hole can't be discussed, but, absent a direct conversation with the architect, the discussion is seriously handicapped if not fatally flawed.
The ODG's were pretty smart cookies and ever cognizant of efficiencies and costs and their relationship to one another.
If a fairway was designed and built to 75 yards, my instinct is to give the architect credit for and credibility in his thinking and efforts.
Over the last 60 years irrigation lines, tree plantings and cost accounted for the great majority of narrowed fairways. Restoring them should be a strong consideration for any club.
I don't think anyone is advocating restoring a 26 yard fairway to 75 yards when the original fairway was 50 yards.
And, I think that's where/why you're getting confused.
That, and talking to TEPaul
