Plumber column
Upright, short offset, face that wants to sit square. Honest on slow municipal grain. On a 11.5 stimp with a west wind off the Peaks, it often over-rotates late. We keep a few for golfers whose arc is almost a straight push.

The neck that leans, then the hang follows
Flow Neck is a hosel shop, not a hang catalog. We start with the throat that connects shaft to head — plumber column, short slant, long flow — because toe hang on a Flagstaff green is a consequence, not a spec you pick from a poster. High-country poa runs out. A neck that sat quiet in the Valley often skids here.
The argument
Hang is downstream of the throat
Most putter talk starts at a hang number because hang is easy to photograph. A flow neck is harder: it is a lean, a throat length, a face that opens on a delay. On Continental and Pine Canyon, that delay is the difference between a ball that dies on the high side and a ball that leaks two cups past.
We still log hang. We log it after the neck is chosen, the way a mill logs grain after the board is cut. If someone walks in asking for “thirty-five degrees of hang,” we ask which throat they think produces it, then we put both on a rail and watch Flagstaff roll disagree with the catalog.
Three throats we actually keep
Not every hosel belongs at this altitude
Short slant
A compact lean. Hang without a long throat. Good when a golfer already has a quiet face and only needs a little toe to follow. Popular with NAU faculty who play Aspen Valley on weeknights.
Long flow
The signature. The neck that delays the face, then lets the toe catch up through the last eight inches. Built for greens that run out — the ones you can see from Birch when the snow line is still on Humphreys.
Birch room
Suite 9, under ponderosa, not a warehouse bay
The shop sits on East Birch, a short walk from downtown brick and a long way from valley humidity. One rail, one copper-top bench, north glass that shows the Peaks when the monsoon is not sitting on them. You bring the putter that currently lies to you. We do not start with a wall of heads.
Monday the door stays locked. Tuesday through Saturday the clock runs 10 to 6. Sunday is a short window, 10 to 2, for people driving up from Sedona before lunch.
From the envelopes
What golfers wrote after a lean
“I came in with a plumber I loved in Mesa. On Continental it would not die. They put a short slant on the same head length and the high-side miss went quiet.”

More of the ledger lives on lean notes. If you want the clock and the copper hook, ask for a lean and a bender writes back from neck@flowneck.space.
