K3 Line
Kastaplast's base plastic. Very grippy in all conditions thanks to its slightly textured surface, with a feel halfway between soft and firm. It beats in faster than K1, which over time makes it a little more workable. Compared with other base plastics on the market, K3 is among the most durable in its category. In the Berg specifically, K3 flies a bit more stable than K1 and lands with much less ground play.
