A club fitting session is usually an hour, maybe two. If you spend the first thirty minutes establishing baseline numbers that you already know, you've spent half the session on something a bit of prep could have skipped. Showing up with your own data doesn't replace the fitter's expertise — it just means the time gets spent testing and refining instead of discovering.
What to bring:
- Your current swing speed, ball speed, and smash factor for driver and irons
- Launch angle and spin rate, ideally averaged across a few swings rather than your one best shot
- Your current carry distances by club, and where you've noticed inconsistent gapping
- A short, specific list of what you want to test — not just "hit some drivers," but "test whether a lower-spin head helps my carry" or "check if I actually have a gap between my PW and GW"
What to ask:
- What specific number is this recommendation solving for? A good fitter can point to a launch, spin, or dispersion number, not just a feeling
- Can I see my before-and-after numbers side by side on the monitor, not just hear a summary
- What would change if my swing speed changes 5 mph in either direction — is this fitting robust to that, or does it assume I stay exactly where I am today
- Did we check ball fit? It's the cheapest change in the bag and it's easy for a fitting focused on clubs to skip past it
None of this is about being a difficult customer. A fitter who's confident in their recommendations will welcome specific questions — it's the fittings built on guesswork and upsell that tend to prefer a golfer who doesn't ask. Bring your numbers, bring your questions, and treat the session as confirming a hypothesis rather than starting from a blank page.
