I'm not real sure why we're discussing this, because the believers and non-believers are pretty much anchored in in place.
However, I've been trying to come up with a way of 'splaining why it's so.
So here goes:
~400+ years ago golf was mainly about avoiding trouble, and every shot except the last few on a hole had that goal.
Fast forward to the Golden Age when the architects started talking about "strategy," which most everyone here claims to believe in. If I understand it correctly, a great strategic course gives golfers choices on almost every shot that are going to have a big influence on the succeeding shot.
Get a shot in the right position and you're REWARDED for your achievement with a chance to make a lower score. Of course this is also true of avoidance shots, but the reward is really delayed.
But even on "strategic" courses, a lot of tee shots on long holes were about avoiding trouble, and hitting it far enough to make the next shot strategically interesting.
For a player who drives it 150-195 yards off the tee, any hole longer than 290 for the shortest players and 375 or so for the longer of them means that most second shots, and a whole lot of third shots simply cannot have much in the way of strategic interest.
When those shots are about avoiding trouble and getting maximum distance, they absolutely become less strategic and less interesting.
If you're one of those players, you only have to play a few rounds on a course that better suits your ability to hit it for distance to realize that the game becomes MUCH more interesting strategically.
This is why elite players hate par threes that require a fairway wood, and par fives that are essentially unreachable.
And, for those who know women and senior men who won't move up, I've known pleny of them too. The simple answer is that they haven't tried it with an open mind. I used to play with a bunch of seniors who were BAD golfers. Except for me, the lowest handicap most days was 20, and the majority of them couldn't hit it 180 off the tee.
One other guy and I started playing up one tee, @5800 or so. Then our Men's Club match play league started letting anyone 65 or over play those tees. Within a couple of months that group was playing the shorter tees every day.
And they all said golf was more fun.
The following isn't about topic, but is another explanation of why some players won't move up.
But there is a problem. Regardless of what Garland says, players who move from a course that is too long for them, to one that allows them a chance at getting on in regulation will see a drop in their handicap. And even with the adjustments made when they play longer courses, they'll be giving up shots.
The simple fact is that the GHIN system is broken, and it's not going to be fixed any time soon with the new global handicap initiative.
A perfect example is mt mother, who played into her 80s. She played Mesa CC for years at 5800 yards for the shortest tees, but once a year we had a family event that was sometimes played at Red Mountain Ranch where the forward tees are Alice Dye-inspired 4800 yards.
At that distance, she couldn't be beaten. And the women of MCC have a record in interclub matches that has to be unmatched.
Anyone who plays much competition at handicap on a wide variety of course knows this is true. There's simply not enough difference in course rating and slope between difficult courses and easy courses.
Another example is Brauer's course in Manhattan KS. I've played interclub matches there and their players were carrying indexes that made them virtually unbeatable. My opponent and I had similar indexes and if he played his everyday golf at my home course he'd be giving me 4 or 5 shots. Our team, which had a very good record in such matches got murdered.
