Strong but light in weight, PST Fuji Tip Tops are perfect for spinning rods or lightweight conventional rods. Fuji PST tips utilize Silicone Carbide rings - one of the most advanced ceramics on the market today. Diamond Polished SiC rings are mounted directly to the gunsmoke anodized stainless steel frame of the Fuji PST which reduces weight, increases heat dissipation, and intensifies line sensitivity.
