Red Dragon Gerwyn Price Switch Darts - Steel Tip - 90% Tungsten - RD-Ultra - 23g. Crafted around the game of a former World Champion, the Gerwyn Price RD-ULTRA is a 90% tungsten steel tip dart cut with an intricate grip pattern never before seen on a dart, its silver machined detailing flashing through deep onyx and metallic blue. One of a kind, built for the Iceman. Built from 90% tungsten, the RD-ULTRA is a parallel barrel with a rounded front and centre weight distribution. The grip zones of Gerwyn's Originals are re-cut with an intricate, precision-machined pattern in place of the buttress, locking in under the fingers and delivering a genuinely new feel, total control and a clean, consistent release.
