I agree Adam, but I do not think you have to think in terms of compromise when talking about maximizing turf. At one course where there is 42 acres of bent fairway the chemical budget one year was $30,000 and the maintence budget was held close to $650,000. Same year, similar climate there was a course loaded with trees and poa and half the acreage of fairway and the chemical budget was $120,000. That is what I mean by creating the conditions by which the groomed turf can thrive and the large amount of groomed turf becomes less an issue and you do not feel the need to compromise the "lines of charm" philosophy". Once the course is built you have committed to a strategic design that probably will not be modified for a very long time, so to compromise the play area because of maintenance concerns is just as dangerous, probably more dangerous a path than the path of maximizing the amount of groomed area.
The approach I liek is to line the fairway edge with the irrigation heads, allow them to be full circle (Toro now has a 360 degree adjustable head) to grow the fairway and rough then adjust the heads to irrigate the fairway only. the roughs receive no water or fertilizer other than by nature. This helps concentrate your resources on the groomed areas. It is a waste of resources to have groomed roughs particularly if you have wide fairways that correspond to many options for play. Rough should be rough. It does not have to be heavy. In the northeast you seed roughs at a much lighter rate than what is recommended and you will still have that wispy, rustic fescue look but it will be much thinner. As you go farther out you seed with the warm seasons: bluestems, broomsedge, wild rye, switch grass, and you get that wonderful eastern Long Island look or midwestern prairie look, and again you then can put all your resourses toward the play areas.
