"Shoot like clockwork" is the statement of a very successful aluminum-carbon archer about this arrow.
And that's exactly what this arrow represents. Extreme repeatability of the shot (enormous accuracy) is probably the main reason for shooting aluminum-carbon arrows.
Aluminum-carbon arrows have a "core" made of aluminum - coated with high-quality carbon.
The advantages
Very high-quality components, precisely adjusted spines, very smooth flight behavior (even in wind), almost indestructible
The disadvantages
The price - Due to the various components, the arrow is relatively expensive to manufacture
With which bow
Aluminum-carbon arrows are primarily used by recurve, barebow, and compound archers. The precise shot guaranteed with this arrow combines the "best of both worlds (materials)" in one arrow.
Conclusion
Carbon-aluminum arrows are for specialists. Recurve, barebow, and compound archers love these arrows for their accuracy and excellent adjustability.
