Yo-Zuri Topknot Natural Clear MainLine 200 Yards is one of the newest fluorocarbon fishing line products from Yo-Zuri. The TopKnot Natural Clear MainLine is abrasion resistant and super durable, meaning it maintains clarity even after extended use. This allows the angler to get even more strikes on the same line. However, this product's most exciting feature is the diameter to strength ratio. The TopKnot series offers the strongest possible breaking strength with an even smaller diameter than before. This is a must have fishing line for any angler!
