SA’s fluorocarbon stands out as one of the better materials out there. The price, while slightly less than GrandMax, reflects its high quality. We heard through the grapevine that Seaguar extrudes SA fluorocarbon for Scientific Anglers. We found it interesting that the knot break strengths were not identical to GrandMax however, suggesting to us that perhaps Seaguar keeps very best “double structure” fluorocarbon formula for themselves.
