On Point verdict
Black J21 04 is worth a look if you prefer a front-loaded bomb profile with both smooth and cut contact areas. We’d choose it for that fuller shaped barrel and the combination of rings, axial cuts and milling. Players coming from a parallel dart should compare where the curved section sits beneath their fingers.
