The house argument
Why a plumber’s neck stalls at 7,000 feet
A plumber column is not a sin. It is a throat that wants the face square and the hang quiet. On slow rye that is a gift. On a Flagstaff green that runs out, the same square face often rotates late — after the ball has already left — and the putt leaks.
What a plumber column is
A mostly upright hosel, offset you can see, a look that photographs as “classic.” The shaft centerline sits behind the face enough to feel like a blade even when the head is a small mallet. Hang is usually modest because the throat does not lean. Golfers who push the ball with very little arc often belong here, even in Flagstaff.
The stall shows up when the stimp climbs and the golfer still has a little arc. The face, trained to sit square, does not wait. It catches up in a hurry through the last eight inches. On a Valley green that extra rotation dies in the grass. On Continental in June it is two cups past.
What a flow neck is
A lean. The throat travels forward and down, a slant you can see from address. That geometry delays the face and lets the toe follow. Hang is higher because the neck produced it, not because someone bolted a weight in the toe and called it a day.
Flow is not magic. A golfer with a straight-back push can over-wait and pull everything. That is why twin geometry exists. We put both throats on the same length and let Flagstaff roll pick.
Altitude
The green is the third throat
Thin air and dry poa change roll-out. Shade under ponderosa changes it again. A column fitted on a humid, slow Bermuda in March is a different machine on a 11-plus Flagstaff stimp in August. We are not anti-plumber. We are anti-importing a Valley throat without asking the Peaks.
Longer notes: plumber column on Peaks turf and stimp at seven thousand.
