If you're a "monofilament" angler who continues to ignore today's superlines, you might want to examine what top pros were fishing last season.
Remarkably, only three anglers among those finishing first and second place during the 14 Elite and Major events used mono exclusively. Beyond that, line usage was fairly equal between fluorocarbon and braided superline.
Does that mean monofilament is dead? Not hardly, but it does indicate the pros are discovering applications in which modern-day lines perform better than traditional monofilament.
