KastKingKovert Blue Water 100% Fluorocarbon Fishing Line, Clear Fishing Leader, Extreme Clarity, Fast Sinking, Shock Resistant, Ultra-Low Visibility, Invisible Underwater, High Abrasion Resistance

Seems like a decent product. First time using fluorocarbon and it's heavy test so not sure if it's normal but product seems very stiff and hard to cinch down knots

Been using kastking products from reels to fishing line and now the leader I must say it is awesome and great value. Well be a repeat customer

This is a high-quality line I would recommend to anyone

Good basic leader line

I got this to use for tying bottom rigs.It's strong and seems to have low memory.The picture is 20lb in water it sinks quick and should disappear in the water we'll.For the price it's going to be tuff to find a better leader material.

Fluorocarbon leader, 100lb test as advertized. Will make good leaders for fishing trip to Ontario this season.

This leader material held up good around rock. I intentionally ran it across rocks on retrieval and line was still smooth. You need to put some pressure on it to rough it up. Its priced right around the Berkley Vanish Fluorocarbon. Quality line that i am not afraid to tie on my braid.

soo far some of the best fluorocarbon iv used. Does just as well as BlueLable from the competitor. Pulled out some nice 22inch + Halibuts a couple time using the same 25lbs line and it handled the abrasion and them sharp teeth like a champ. So yea i will be buying this line a lot more to keep testing its limits to prove to my buddies its just as good if not better than some of the other brands out on the market.
