Strength and durability even with very fine diameters. The new surface treatment reduces friction, which is easily noticeable during casting as the friction noise on the reel is almost non-existent. The knot strength of the shock leader, whether made of nylon or multifilament, is very high and the line does not "compress" near the knot. The characteristics of being memory-free and resistant remain unchanged for twice the duration compared to regular monofilaments, allowing you to use the same line for the entire competition season without needing to change it.
