The Titleist TSi1 fairway wood covers 15° to 23° across 4 factory loft options, giving it a 8° broad range. The typical loft step is 3°, so the lineup moves from a stronger fairway loft into progressively higher launching options without relying on identical spacing.

TSi1 Fairway Wood loft flight map
The bars place each option on the same fairway-wood loft scale. Lower loft leans toward tee distance and a flatter flight; higher loft usually becomes easier to launch from turf and lands steeper.

How each TSi1 Fairway Wood loft changes the shot
| Club | Loft | What that loft changes |
|---|---|---|
| 15° option | 15° | This sits in the strong fairway zone, with a flatter flight and more tee bias than the higher-loft options. |
| 18° option | 18° | This is the versatile middle of the fairway range, balancing useful tee distance with better launch from the turf. It sits 3° above the previous option. |
| 20° option | 20° | This moves into higher-launch fairway territory, with more stopping power and easier turf launch. It sits 2° above the previous option. |
| 23° option | 23° | This is a high-loft fairway option, aimed more at easy elevation and green-holding flight than maximum distance. It sits 3° above the previous option. |
For fairway woods, the useful question is not simply which loft goes farthest. The better loft is the one that launches reliably from the lies you actually use and leaves a clean carry gap to both the driver and the next club down.
