On the light bream stuff it makes a massive difference, im not sure in the deep blue tho. Go down the river on a sunny day and throw artificials with 2m of fluro and 2m of standard leaders and see if there is a difference in bite rates. Bait fishing it wont make a difference imo

 Definetly worth it.. if only for its abrasion resistance. Might be harder to work with, but if you use an FG from braid it has no ill effects. Seen plenty of soft nylons like jinkai rub through when dhus inhale plastics - fluoro is tough 

I was fishing for Pilch (Yellow eye Mullet) alongside my son a few years back.  He was using fluorocarbon and me nylon and he was getting heaps and me none. I grabbed some of his fluorocarbon and tied another rig and started getting them straight away.  I'm a convert now and use it always, even for offshore fishing.   Not sure it matters in the deep, but may as well use it.

Thats pretty good proof there Bellyfish, I need more convincing tho! was your original line diameter thinner or thicker than the flouro you changed to? 

If it works, anywhere the light reaches FC should have an advantage i reckon.  

Have a read here:

I can't comment personally as I've never used it.  If I was to fish super light line I think I would try it to see if there was any noticeable difference in hook ups.

Cheers Alan thats the article im talking about. I probably read it for the first time when you posted it back then!

 I find it works a few situations. Very light lure fishing, light jigging and fly fishing. All for the abrasion resistance really so I can run very light leaders.. Do I believe it reflects light etc, not really and its only a plus if it does 

For any type knot . I have tied a few over the years .from trout to deep sea . Only my opinion. It’s brittle always breaks under pressure . Try one thing . Do your fg knot. Do a snell rig . Or whatever knot you do . Hold up to light you will see fractures going through line . Take few different lines around high 30s (dive )stand out more so than green or clear mono . Only my thought . Don’t need it .

Personally i find FG is a lot stiffer and the dfiference in thickness between a say PE0.6  8 ply braid tied to a 6lb FC via FG knot still gives me wind knots. This problem amplifies itself when you are working topwater lures where there's slack in the line. The FG almost always ends up kinking and forming a knot by itself. However, if I use a stiffer 4 ply PE 0.6 then the problem is less noticable. The limp 8 ply braid doesn't sit well with the stiffer FG when you pelt out a cast really hard. This problem is more prevalent in hardbodies than soft plastics...for some reasons.

I put it down to the difference in thickness & stiffness of the line. 

 I tried cutting down the number of wraps on my FG knot but the problem still doesn't go away. Mind you I am using a rod with FUJI K Guides.

 Hence, I have been casting for tailors/salmon/herring in the river using el cheapo mono and never had a problem since. 

 However, I will still stick to FC line when jigging for the abrasion resistance.

 I started off with mono, switched to fluoro, now I'm back to mono.

I can't see any advantage to fluoro, and the stiffness is a real disadvantage.

Watch this video if you want to see some real experiments that test the abrasion resistance of both: https://www.youtube.com/watch?v=KiQTvmM-1cY

(spoiler, mono beats fluoro in abrasion resistance)

Wouldn't use anything else when squiding..

heavy rigs as in my beach rigs or out

bit deeper I don't bother .. recent trout

trip was using 6lb braid too 8lb Fluro .

perfect ..  cheers pirate.
