Best producing leader for rigging.Great line for making rigs and using as a leader. Unless a sharp toothed fish such as a mackerel, bluefish or shark snips your line like a pair of scissors you should have no problems. I have brought in 40 inch redfish on 20lb flourocarbon right after landing a 36 inch redfish before it. Besides sharp toothed fish cutting the line, this prpduct holds up great against snags, fish and general use. It provides more bites than braid or monofilament. Be sure to check for frays just like any other line between each fish.I use this line for live bait, making rigs, trolling, jigging, and any other use I can think of and have caught hundreds of fish without going through my first spool of 20lb line.For smaller fish go light, you lose lure action and finesse as your line diameter increases. I will be buying this product again.0
