We have been using Opsin for about three years now, and we have never looked back. I love the fact that they offer flourocarbon as small as 6 and 10 pound all the way up to triple digits. We have yet to have any of our lines fail. Honest to God!

Owner responded to my order within 5 minutes of purchase. Couldn't ask for anything better.

I used the 20lb Opsin Fluorocarbon earlier this summer to catch back to back White Seabass 16lb and 18lb at the Coronado islands. These were my first White Seabass in 20 years.

The 40lb fluorocarbon line worked well on bluefin and surface iron yellowtail fishing. I am now using this line for deep water yoyo yellowtail, lingcod and other rockfish. I also use, 15lb thru 130lb Opsin Fluorocarbon fishing line.

Fish Opsin for yellowtail, amazing product never change the leader coughs 5 yellows on the same 25 lb leader

I just started using this line I like it I fish a lot on crowded boats my line is constantly rubbing against either the boat or someone else’s line although I check my leader often this line just doesn’t seem to fray up as much

I tie my jigs directly to the flouro.I lend my gear a lot as I charter and bring my friends!My past trip we caught almost limits the biggest was 99.4 dresses we lost one fish to breakage but that was an angler error

I used Monofilament and was Skunked. Next Trip, with Opsin Fluorocarbon, I caught the first Fish, with 33 other Fisherpeople.

Love it!! Best line I’ve ever used

Very good product. Have now used 15,20,25,30,35,40,&50 with success. Have 60 too but unused. All have superior knot strength and smaller line diameter than competitors. Got 5 bluefin and 6 yellowfin on my most recent trip using opsin!

Super stoked on this package! Already caught 30-40 pound yellow tail!

OPSIN ROCKS!!! Started using it last season and now that’s all we use!!! PERFECT FOR BLUEFIN, YELLOWFIN, YELLOWTAIL, and DORADOS!! We LANDED a 100lb BlueFin on 35lb Fluro on our Light Outfit:
ROD: Seeker Black Steel 15 - 20lb 8FT
REEL: Diawa Lexa 400 TW
BRAID: 40lb
Thanks Greg!!!

This line made the difference on a tough fly line note for 30-40 lb BFT. I didn’t break any off and landed 10 and passed another 3 off. Great line. Much more flexible and than the seaguar blue and much stronger than gold

This line really made the difference on my last 3 day trip out of San Diego. I was the hot rod landing 12 Blue fin to 40 pounds and 4 yellow tail to 25
