High density PE (high density FEP is used for the core wire). "8+1 structure" of 8 PE strands + 1 FEP. The sinking PE changes the way you attack. Muscle PE (high density PE). The quality of the thread is significantly improved by being densely woven (compared to our company). "Resistant to abrasion/Improved durability/Reduced noise/Increased casting distance". - "TOUGH PE" x "NEW Evo Silicone2" = Abrasion resistance 300% or more (compared to our company) - TOUGH PE ⇒ The raw thread is thicker and more round, increasing power. - New Evo Silicone2 processing ⇒ Improved durability/Smooth and reduced noise. - UVF processing (ultra-high density fiber processing) ⇒ Stronger, more sensitive (compared to our company) - Muscle Braiding ⇒ Densely woven to be resistant to shock breakage.
