Red Dragon Gerwyn Price Darts - Soft Tip - 90% Tungsten - RD-Adv - 18g. Take hold of the Originals and feel the difference. The Gerwyn Price RD-ADV is a 90% tungsten steel tip dart with silver buttress micro-grip grooves running the full length of the barrel, finished in silver and metallic blue and powered by Switch Points. This is where your control starts to sharpen. Built from 90% tungsten, the RD-ADV is a parallel barrel with a rounded front and centre weight distribution, taken from Gerwyn's Originals. Silver buttress micro-grip grooves replace the Gezzy Signature V cut and run across the whole barrel, delivering a secure hold all over the dart without losing the character of the Originals.
