Iron Fitting

Irons rarely get the multi-position ports a driver has, but most carry a single fixed port or a tip-weight system — and that hidden weight is exactly what drifts out of tolerance over years of regripping and bag abuse.

Set-Wide Audit

We Weigh Every Iron, Not Just the One That Feels Off

A single mismatched port in the middle of a set throws off swingweight progression for every club around it, so we pull and weigh every iron in the bag rather than only the one you flagged as the problem.

Dynamic lie angle gets checked at the same time, since a port issue and a bent lie angle produce similar-looking dispersion on paper but need two completely different fixes.

What We Check

Three Things That Hide Inside an Iron Head

Tip-Weight Consistency

Cavity-back irons with an internal tip weight can vary between individual heads even within the same model year — we check each one rather than trusting the label.

Port Screw Torque

Loose port screws don't always rattle audibly, but they change effective swingweight and can back out further with repeated play.

Cross-Model Set Makeup

Mixed sets built from two different iron lines often carry mismatched port designs entirely — worth flagging before a gapping problem gets blamed on the swing.
