About SpecMyBag

What this site is

Most golf equipment content answers a question you did not ask. You want to know what loft driver to buy; you get a list of the best drivers of the year. You want to know which wedges fit your irons; you get a 52 / 56 / 60 recommendation written by someone who never asked which irons you own.

This site does the opposite. It asks for your numbers — swing speed, ball speed, height, wrist-to-floor, and the pitching wedge loft of the set already in your bag — and returns the specifications those numbers produce. Driver loft, shaft flex, shaft weight, club length, lie angle, and a complete wedge ladder. Then it points you at the clubs built to those specifications, mostly on the used market.

What the expertise here actually is, and what it is not

This matters more than the usual credentials paragraph, so it is stated plainly rather than implied.

What this site does have

• A specification database. 201 iron sets from 16 manufacturers, 2016 to 2025, compiled from manufacturers' own published specification tables. Their pitching wedge lofts run from 38° to 47°.
• Published fitting and launch-condition research. The relationships between ball speed and carry, between attack angle and the loft you need, and between wrist-to-floor and lie angle, are all documented in the open literature and in manufacturers' own fitting material. They are cited where used.
• Arithmetic that is shown, not hidden. Every result on this site comes with the reasoning that produced it. Where a number is a band rather than a point, it is presented as a band.

What this site does not have

• No launch monitor. No club has been tested here. There are no first-hand test results anywhere on this site and there never will be unless that changes and is stated.
• No fitting bay, no premises, no fitting business. There is nothing to book and nothing to sell you directly.
• No claimed certification. No fitter qualification, professional-body membership or industry credential is claimed, because none is held. Articles are published by SpecMyBag Editorial, the site's editorial entity, and not attributed to an invented individual.

The limits of a static fit

Everything here is a static fit: measurements taken standing still, turned into specifications. A static fit is genuinely useful, because it gets you to the right head, the right shaft category and the right build sheet before you spend anything. It is how you avoid buying a 9° driver at 82 mph, or a set of wedges that leaves a thirty-yard hole.

It cannot do everything. A lie board and impact tape settle the last degree of lie angle, because how you deliver the club matters more than how you stand. A launch monitor settles spin. Neither of those is a reason to skip the static fit — they are the step after it.

Why the database is the point

The arithmetic on this site could be copied in a weekend. The database could not. Modern pitching wedge lofts vary by about five degrees between models — strong-lofted sets sit near 43°, players' sets near 47°. That gap is an entire wedge. Nobody can correctly answer "what wedges should I carry" without knowing the loft of the specific set a golfer already owns, and those specifications are fragmented across every manufacturer, inconsistently named, and replaced with new releases every year.

Keeping that database accurate and current is the actual work here. Every set carries a status: whether its figures have been re-confirmed against the manufacturer's own published table, and when. That status is shown to you in the tool output rather than hidden.

How this site makes money

Affiliate commission on golf clubs, disclosed on every page that carries a retailer link, and set out in full on the affiliate disclosure page. The recommendation is produced by the arithmetic before any retailer is involved, and no retailer has ever paid for placement or influenced a specification on this site.

Corrections

If a specification here is wrong, it is worth more to this site to fix it than to defend it — the database is the only asset here that matters. Tell us what is wrong and where you checked it, and it will be corrected and the check date updated.
