One thing theoretical (and some real) architects miss is that every fairway bunker may affect the D player in their second shot as well as their first! This got hammered home to me playing La Costa Champions with press, average players, and wives, after our renovation.
We reduced bunkering to 138,000 SF (still an ungodly number) including some at different distances. The number of times less skilled players topped their second shot into the bunker was staggering. I can report it wasn't very much fun for any of them, and it led me to my current opinion of not littering any fw with bunkers. (well, most, always room for one or two)
The general premise of locating fw bunkers include the fact that we can somehow predict how far golfers are going to hit it. But, as someone noted, there are many 230 yard drives, hit poorly by 260 hitters, etc. So, even accounting for wind, uphill/downhill, roll, etc. for someone who is reasonably consistent (enough to consider strategy) is hard enough.
Trying to locate a bunker to challenge a mediocre golfer who will probably top one in four tee shots is harder yet, and who hit their max tee shots about 180, but may only go 150 another quarter of the time, making it a low value proposition design wise, if on a budget, and maybe if not! How would I know which hole they will hit it full on and put bunkers there?
Not to mention, for them, a good shot is airborne, more or less in the right direction, and at least 90% of the distance they hoped to hit it. Based on playing with average golfers, I believe their expectations are that that shot shouldn't find its way into a bunker I thought might challenge them, it ought to roll as far as it can so they can enjoy it.
Does anyone have any real world experience often playing with average golfers (who aren't architecture buffs) that is significantly different?
