When it comes to a supple monofilament with minimal stretch, Sufix Advance excels. With Sufix Advance, you can be confident in landing the fish you are pursuing. Sufix Advance monofilament, with its low stretch, is the perfect line for casting hard bodies off the rocks or any type of trolling for inshore and offshore.
