The 3-wood question: who should actually carry one
The most-bought fairway wood is the one fewest golfers can use, and the data says so plainly.
The 3-wood is the default second club in the bag, and for a large share of golfers it should not be. A 15 degree head needs launch conditions most amateur swings do not produce off the ground, so the shots come out low, land flat, and run wherever the ground sends them. The on-course data makes the case better than any opinion, and it is the reason good fitters make players earn this club before fitting one.
Tracked amateur rounds show the 3-wood out-carrying the 5-wood by 24 yards at scratch but only 12 yards at a 25 handicap, while the 5-wood to 7-wood gap shrinks from 14 yards to 4 over the same range. At slower speeds, three fairway slots are doing the work of one and a half, and the lowest-lofted slot is the one contributing least.
Fitters have converged on the same answer from the bay side. One national-chain fitter requires players to demonstrate a well-struck 15 degree 3-wood before he will fit one, and reports the 5-wood carrying longer for almost every type of player who walks in. On the robot, the 3-wood turns out to be the only fairway wood that loses carry when the strike gets steeper; every higher loft gains from the same move. So a golfer with a downward strike is not fighting a skill gap when the 3-wood misbehaves. The club and the delivery are simply mismatched.
The tour picture is telling in the other direction. The measured gap between driver and 3-wood carry is 23 to 32 yards at tour speeds, which is what the 3-wood costs in exchange for its findability. Roughly one tour player in eight carries something more lofted than 15 degrees as their longest fairway wood, and the mini driver exists precisely because the 3-wood's job off the tee is better done by a bigger head, while its job off the deck is better done by a smaller loft number than its own.
What replaces it is not exotic: a 5-wood or 7-wood for the deck, and nothing at all if the slot was only ever hit from the tee twice a round. The higher-lofted wood turns the same swing into height, carry, and a landing angle that holds something. The cold top, the 3-wood's ugliest miss, mostly disappears because the extra loft gets the leading edge under the ball.
This engine follows the fitters rather than a speed chart: it never retires your 3-wood because of a number on a swing-speed table. It looks at what the club actually did, height, descent, and flight shape, and only says the slot is not earning its place when the measured flight says so. The exact height and descent floors it uses are practitioner judgment, stated as such, and they are the kind of threshold in-person fitting refines further.
