The weight steps across Heta's ranges are deliberately uneven, and worth knowing before choosing. From 21g to 23g the barrel widens a full 0.4mm; from 23g to 25g it adds only 0.2mm — so the lightest option is the most distinct of the three.

The Natural is bare tungsten with no coating at all, which ages differently to a finished barrel: it takes on a polish where your fingers sit rather than wearing through a finish, so the dart ends up showing you exactly where you hold it.

Across the generations the dimensions stay close — 50mm barrels running 6.6mm to 7.3mm — and what actually changes between them is the grip intensity and the finish rather than the shape.
