Late to the fray but... Frank you do realize how few people actually CARRYthe ball 150 yards a majority of the time.
and that doesn't even incluse the foozles, tops, slkies etc.
150 yard carry would probably equate to a 170-200 yard drive depending upon trajectory and lower clubhead speed would produce less spin.
I can't think of many golden age courses where one HAS to CARRY it 150 yards assuming there are shorter senior and or forward tees available.
Are we going to banish 95 % of all women and seniors BACK to the pitch and putt?
I grew up at Augusta CC-the longest carry there if you played the white tees (before there were senior tees) was about 10 yards,except for par threes-with one carry about 100 yards over water. Next door, at ANGC the longest carry would be number 12-about 130 yards, but one can lay up-like Spieth did
At Southampton and Palmetto, two golden age greats where I'm currently a member,the longest carry of the two courses is about 100 yards (at most) on #3 at Palmetto-though there's now a senior tee with about a 60 yard carry and a forward tee on the other side.
I played a pro-am last year with 4 seniors who were all avid golfers and active members-they had 19-28 handicaps and were all over 70. For some silly reason they had everyone play the back tees (the cousre was about 6500 yards and a decent Golden age courses) but these guys couldn't carry it or hit it high enough to reach most of the fairways and there solid drives got eaten up in the rough 90-120 yards from the tee-often on an upslope-often right next to the tee they usually play. After a wedge they still were
laying 2 100 yards where there normal bullet from the forward tees would've been.
My point is these were active decent golfers who had their day ruined by 100 yard (uphill carries) and 130 yard level carries.
In this case the answer was simple-play the regular senior tees.
But for someone to assume someone who can't carry it 150 yards is a beginner(man or woman), is incredibly naive.
designing courses for them assuming appropriate tees isn't dumbing things down, it's something that's gone on for years, and is essential to enjoyment of the game-for everyone.
