Compare standard OZ.1 and OZ.1i in the right length and lie, using the same ball. Choose the aluminium or stainless-insert response from a pace trial, and keep heel-shafted HS models separate from this decision.

Keep the standard OZ.1 family separate from HS
The standard OZ.1 uses an all-aluminium head, while OZ.1i combines an aluminium head with a stainless-steel insert. The manufacturer describes the insert response as firmer and faster. These standard models form the face comparison here; heel-shafted OZ.1i HS and alternative-length builds need their own identification.
Both stock pages list 33-, 34- and 35-inch lengths, a 69° lie and 2° shaft lean. Treat those as offered specifications rather than a prescription. First establish what fits your setup, then compare the face options in a build that lets you make an ordinary stroke.
| Decision | Evidence you need |
|---|---|
| Does the standard OZ shape suit you? | Comfortable aim and setup in the correct length and lie |
| Do you prefer insert or aluminium response? | Pace trial with the same ball and comparable build |
| Is stock suitable? | Match the offered specification to the fitting |
| Is a custom option worthwhile? | A concrete fit or preference reason for the extra cost |
| Is the UK offer complete? | Delivered price, exact model and clear seller terms |
Begin with the head shape and aim
Use your current putter as a reference and compare short starts before concentrating on long-putt pace. Notice whether the alignment picture helps you settle into a repeatable setup. Avoid changing posture merely to make a stock demonstrator sit flat; a fitter can help determine whether its specification is appropriate.
If the shape is not comfortable, trying a different face material may leave the main problem untouched. Conversely, if the head suits you well, a careful face comparison can help decide which version to order without reopening every part of the fitting.
Compare response at several distances
Alternate short groups with the same ball. Include longer putts, uphill and downhill where the practice area permits, and keep the intended finishing area consistent. Look at the size of the normal distance errors rather than selecting whichever version produced a single holed putt.
Write down how the strike sounds and feels separately from where the ball finishes. A firmer sensation can be a welcome preference without demonstrating better pace control. Give yourself a little time with each response before calling an unfamiliar sensation a performance problem.
Protect the fit when choosing stock or custom
L.A.B.’s official guidance provides fitting and retailer routes. Use the current process and get the final length and lie recorded. If the stock putter does not match that recommendation, discuss the appropriate order rather than assuming it can be adjusted routinely after delivery.
Check shaft, grip, alignment and any other selected option against the trial putter. A custom colour may be enjoyable, but it does not resolve an uncertain fitting specification. Price the build that answers the fitting first, then decide whether optional appearance changes are worth the added cost.
Make the UK transaction clear
Ask where the putter ships from, which business sells it and what the complete delivered amount includes. Confirm the exact model name so OZ.1i HS is not substituted for standard OZ.1i. General website build times are not a commitment for your handedness and chosen configuration.
For a used offer, request its original specification and modification history. The L.A.B. guide covers broader buying checks, while the lie-angle balance guide explains the design context. Neither implies a guaranteed improvement from changing to this family.
