Furnace air and a quicker 8-iron

Kansas winter is a dehumidifier with a prairie attached. Furnaces run. Indoor relative humidity in a Wichita house can sit in the teens. Graphite epoxy and the resin in a composite hoop do not love that. They shed a little water, they stiffen a little, and the microphone writes a higher number than the one we inked in September. Steel is less dramatic, which is why a mixed set can feel like two companies in February even though nobody changed a tip.

Players describe the sensation as dead because the ball flight looks lower or the club will not wait for them. Dead is a feeling word. Frequency is a count. On this rail, dry-air weeks more often raise CPM than lower it. That is counterintuitive if your mental model is “cold equals floppy.” Cold is a different error, and we handle it by making the bag sit until the heads are no longer fence posts. Dry is the furnace. We log it.

Why the sheet has a humidity line

Without a hygrometer note, a January recert is an argument. With one, it is a comparison. The header on every work order carries dry-bulb and relative humidity next to the master-bar CPM. If your September sheet says 42 percent and 284 on the bar, and your January sheet says 18 percent and 284 on the bar, we can talk about the clubs rather than the room. If the bar itself moved, we stop and look at the vise. We do not chase a two-cycle “problem” that is just the building.

The winter recert exists because people keep their irons for years and the prairie does not. It is a shorter visit than a first Neighbor Match. We are not rebuilding the philosophy. We are asking whether the stair you paid for in 2024 still describes the tubes in 2026 after two furnace seasons and a summer in a garage. Sometimes the 8-iron has crept a few cycles and still sits inside the eight-CPM neighbor window. We will tell you to go play. Sometimes it has walked far enough to feel like a stranger. Then we talk about a tip or a tube, not about your hands.

What not to do in a cold snap

Do not tick in a driveway. Do not pluck a shaft against a garage door to “see if it still rings.” Do not leave the bag in a truck overnight and then demand a number at 7:05. Marisol will park the heads on the rail. Helene will not override her. A frozen hoop is not a frequency, and a work order written on a frozen hoop is how a hangar earns a reputation for random sheets.

If you stored clubs next to a floor vent all December, say so in the complaint box. That is useful. “They feel weird” is not. We would rather have a boring humidity story than a dramatic flex-letter story. Boring is how you keep a stair honest from one winter to the next. Dramatic is how you buy three 7-irons and still hate January.

Bring last year’s carbon if you still have it. The desk can usually find the scan, but paper in your hand is faster. We will put both headers on the bench and look at the air first, the 8-iron second. That order has saved more bags than any speech about letter flex.
