I had this very conversation with various different people last winter. The answer was simple; in most cases, most of the golfers won't know the difference. For example, how much difference is there between a hand mowed or triplexed approach or tee box. Once they are mowed on the same schedule and height, no one is really going to notice a difference, except for maybe larger lines. Now with saying that, and for the reasons mentioned in other posts I believe triplexing greens should be a last resort.
I've never really got the whole triplexing fairways thing; I understand there may be situations where it is necessary (like drainage issues requiring lighter machines) but for the most part the 5 gang machines use the same cutting units as the triplexes so any arguments of a better cut seem unjustified, again clubs might just like the smaller lines.
As for bunkers unless it's somewhere like PV with vast waste areas or a club with bunkers that are easily accessed, I believe Sandpros can do more damage than good, and while the short term saving might seem great, the long term damage makes it a false economy. Now the need to hand rake every bunker every day (depending on the amount of play) seems excessive and is an option that can be taken into consideration, however if left too long, one that players would notice if they are constantly trashed. Of course this then brings up the whole debate about bunkers being hazards…….
Rodger's PDF shows a great point. As I'm sure you are fully aware, any superintendent can make any budget work however the issue is not getting the course work done but how well it is presented. You can’t expect to buy a new Rolls Royce for Hyundai money…… (They both do the same basic job but look at what the extra buys you) I could maintain my course for 2/3 my budget, but our standards would be nowhere near where they are and although the drop in standards would probably not as noticeable over the first few months it would slowly deteriorate as everything that wasn't getting done compounded.
Which brings me to my final point of things that golfers wouldn't notice but agronomically are very beneficial. An example being spray-hawking greens, it might be an extra labor expense but it is very beneficial for a number of reasons not least keeping the heavy sprayer (and associated tire rutting) off them. Just remember that what is good or works for one club or membership will not necessarily be beneficial to another.
