Van Gerwen has thrown broadly the same slim barrel specification for years, and the range around it has stayed just as stable — Prism flights, Vecta shafts and cases all in the green and black he is known for.

That consistency is worth something when you are buying into a setup. Replacing a component means getting the same thing rather than whatever the current season's redesign happens to be.

The barrels run long and slim, generally 53mm and above at around 6mm to 6.6mm, which leaves as much room in a treble as a dart can. Several offer half-gram weights that exist because he asked for them rather than because a product grid needed filling.
