If a shot starts on one line and then curves sharply away, buying a new shaft before understanding the pattern can make the problem harder to untangle. Begin by recording the starting direction, the curve and the contact point. Those observations give a coach or fitter a clearer question than simply saying that every drive slices, and help distinguish an equipment test from a swing change.

| Observation | Record it plainly | Next question |
|---|---|---|
| Start direction | Left, near target or right | Where was the face pointing at impact? |
| Curvature | Direction and approximate amount | How did face and path relate? |
| Contact | Centre, heel or toe pattern | Could strike be influencing the flight? |
| Equipment baseline | Head, setting, shaft and length | What single change is worth testing? |

Separate start direction from curvature
Trackman's face-to-path explanation defines the relationship between where the face points and where the club travels at impact. For centred contact, that relationship is a key influence on curvature. For a right-handed golfer, an open face relative to the path tends towards rightward curvature; the handedness context matters when using words such as open, closed, slice or hook.
A ball can start left and curve right, or start right and curve farther right. Those are different observations even if both finish in the same rough. Record the initial line relative to a clear target and the later curve separately. Avoid making a diagnosis from the finish alone, particularly in a strong crosswind or when the strike is visibly away from the centre.
Check the setup and the evidence with a coach
Choose a specific target rather than aiming vaguely down the range. Ask a coach to check the relationship between your intended line, address position and actual delivery. A camera can help when placed deliberately, but a casually tilted view can make alignment look different from reality. Keep the same camera position for comparisons and let an instructor decide which view answers the question.
Bring a short record of typical shots, including the clubs involved and whether the pattern changes during a round. A driver-only miss may raise different questions from a curve present throughout the bag. Describe recent changes in grip, club length or equipment settings too. This gives the lesson a concrete starting point without trying to prescribe a universal grip correction from an article.
Include strike in the equipment test
Ask the fitter how contact will be measured and interpreted. If strikes repeatedly miss the centre, a change in playing length or another build characteristic may deserve a controlled trial. That is a reason to test, not proof that a shorter shaft will cure your particular shot. Keep face contact alongside the launch data so a better-looking number is not considered in isolation.
Use your existing driver as the baseline and retain ordinary misses in the sample. If the test club feels easier to deliver but only one swing has been recorded, the result is still thin. Compare several recognisable shots and ask what improved: contact, starting direction, curvature or all three. A useful fitting should be able to describe the trade-off in plain language.
Treat draw-biased equipment as an option to test
The PING G430 SFT is one example of a driver specifically positioned by its manufacturer around shot correction. That makes it a relevant fitting candidate for some golfers, but it is not evidence that it can cancel every face-to-path relationship. Test the actual loft, setting and shaft combination, and include the possibility of a miss in the other direction.
Do not change a sleeve position, grip, shaft and swing cue simultaneously if you want to know what helped. Agree one adjustment with the fitter, record the result and compare it with the starting setup. Keep the final settings in writing. A club that works during a trial is more useful when you know exactly how it was assembled and adjusted.
Spend on the next unanswered question
If you cannot yet describe the shot pattern, an assessment or lesson is usually the clearest next step to consider. If the pattern is understood and a specific equipment change has helped in a trial, a fitted purchase becomes easier to justify. A training aid should likewise support the exercise your coach has identified rather than promise to fix a loosely described fault.
Use our fitting guide to prepare for that appointment. Keep practising the agreed task and recheck the result under normal course conditions, where targets and consequences change. This guide explains the buying decision around a slice; it does not claim to diagnose your swing from a symptom or guarantee that one product will straighten every drive.
