Gary Anderson's Phase ranges are the long slim pencil barrels Unicorn are known for — 52mm and above, holding 6.1mm at 21g, which leaves as much room in a treble as a dart can.

The Pro-Tech range is the one to explore if you are still finding a shape. Six distinct profiles sit under a single finish, from a 40.6mm scalloped teardrop at 8.2mm through to a straight 50mm barrel holding 27g inside 7mm — genuinely different darts rather than one barrel at six weights.

James Wade's barrels run slimmer still at 6.1mm, and Ross Smith's come in bare tungsten as well as coated. Several Anderson ranges hold one diameter across every weight and add mass through length instead.
