Fuji Guides HNSG medium weight guides are perfect for rods that are in-between a light guide and a heavy guide. Based on NSG frames, but with thicker gunsmoke stainless steel material, they provide the strength needed for heavier lines but are flexible enough to bend with the rod. Fuji HNSG guides utilize Silicone Carbide rings which is one of the most advanced ceramics made today. Diamond Polished SiC rings are mounted directly to the frames, which reduces weight, increases heat dissipation, and amplifies line sensitivity. Fuji HNSG guides can be used with Fuji UST tops.
