Gentlemen,
When discussing fairway width, you have to consider site conditions as well.
Take our Sagebrush project, in British Columbia, for example. The scale of place is MASSIVE. And, the property is very slope-y in spots. It's very windy in the Nicola Valley, too. Moreover, the mandate is to maintain consistently firm and fast fescue fairways.
So, aside from strategic considerations, we're forced to provide fairways at Sagebrush in the neighbourhood of 75 yards across (at least a few fairways are even wider, in spots), simply to facilitate enjoyable golf for a majority of players; and also to present proper scale. In other words, sticking a 20-yard wide fairway into the frame we have to work with would look ridiculous.
Same goes with the greens.
Scale-wise, many of the greens at Sagebrush have to be LARGE. Two are over 20,000 square feet, in fact. But, it's really odd, they don't look this big because of the inherent scale of the site. Large greens also work well, strategically, with the ultra-wide fairways. Because the greens offer such a wide array of hole locations -- far-right and far-left, specifically, as they relate to strategy -- golfers will genuinely be presented with advantageous angles to certain hole locations by playing down the margin of ultra-wide fairways at Sagebrush...
Just like the good ol' days!
