For decades, for dry fly fishing, I have been using a 9' 4X tapered leader with a piece of 5X fluorocarbon 3' or 4' long. (or a 5X leader with a 6X tippet)

This year I have been omitting the fluorocarbon tippet and just using a piece of Rio 4X 3'-4' long. I have noticed no difference whatsoever in the amount of rises I have been getting or the number, and size, of the fish landed.

I was wondering if anyone else has experimented with fluorocarbon versus nylon and if so what were the results of your testing.

Probably doesn't make much of a difference at all, but I use it. Mainly because it sinks better. I think in clear water with a sandy substrate (majority of my fishing) it can give you a legitimate advantage because you dont' have a ton of little dimples casting shadows down below from your leader or tippet floating on the surface. Other than fishing dries... whatever. And still, I've caught plenty of trout with dries on a nylon leader. I think once nylon gets a little wet, and you fully get all of the kinks/reel memory out, it still works just fine for dries.

I've seen the tests that purport the superior qualities of fluorocarbon under certain conditions and for certain applications. I guess my view is that fly fishing accessories are a business just like sneakers and if I'm willing for pay for it, there is always somebody out there willing to sell me a $300 pair of sneakers as well as a $15 spool of fluorocarbon.

The question is whether I really need either. So far, I haven't..

I agree about the cost issue. Most spools of fluorocarbon are around $15. TroutHunter is $22.00 which I think is nuts. My buddy has the Orvis Pro guide discount and he can get me the 100 meter Guide spool of Mirage fluorocarbon for $20. That is a great deal. But if I buy three spools of Rio fluorocarbon and it costs me $45 and I buy three spools of Rio nylon for $15 I'm saving $30 which is 2/3 of a tank of gas.

I'll be on my favorite Montana tailwater in 24 days and will try both materials under the same clear water spring creek like conditions and see if there is any discernible difference.

I use mono exclusively for dry flying and switch to flouro for wet/ streamer / nymphs. IMHO, mono works reasonably well for subsurface applications but flouro is slightly superior due to its sinking advantage whereas mono is a little better for surface presentations. I especially notice a difference when fishing for bass using bass bugs/ poppers

I've gone back to mono partly because fluorocarbon does not degrade, which means if I leave a 2' piece of it up in a tree it will be there for a long time, potentially snaring birds etc. I once untangled a titmouse that was hung up in a piece of fishing line, and it wasn't pretty, though he flew off just fine after biting me several times with that sunflower cracking bill. And I've seen photos of other birds that didn't get free.

If I only could use 1 and the other , it would be mono because it’s deficits in subsurface applications as compared to flouro is less than the inverse on top; also, Martin makes a valid point with the wildlife issue. Although I don’t like using shot for streamers and wets because it affects their presentation IMHO, using a sink tip can overcome that and in that case or situation, mono can be used for tippet/ leaders probably as effectively as flouro. For nymphing though, I feel that flouro is superior to get your flies down as quickly as possible for a good and longer drift; moreover, it’s supposed to be less visible to the fish isn’t it?

Louis, you're a good guy. If anyone ever says otherwise, they'll have to deal with me!

Yep, as a kid I always heard "fishing line strangles baby birds!!" and always chopped up my old mono with scissors so no momma bird would try to line her nest with it. Same thing has to happen with sixpack plastic beer rings!! They are killing sea life. Apparently a plastic bag was photographed at the bottom of the Marianas Trench, a.k.a. the deepest spot in the ocean (about 7 miles). Plastic bags kill leatherback sea turtles, who mistake them for jellyfish and eat them until their stomach is literally full of plastic with no room for food...Plastic is actually more of a curse than a blessing sometimes. But until someone figures out how to make fly lines and leaders out of something else (back to silk and horsehair??) we'll be using them, and need to be responsible with them.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Catgut maybe Jonathan? Ha... but that brings me to my original thought after reading some of the replies: there are many ways to skin a cat (contradicting to the original saying, I know). Lol. Some want their tippet/leader floating when fishing dries and some don't. I don't, but maybe if I were to try skating a caddis then I'd prefer nylon. Maybe it also doesn't matter much, but it's fun to think about these things.

*edit* I also keep a reserve pocket in my vest for garbage right by my nippers for granola and protein bar wrappers, and tippet that I snip. Makes it pretty easy not to lose any to the river or woods.

I tested some 4x & 5x fluoro vs mono over a 3 week intense fly fishing. I kept loosing head-shaking large trout almost instantly with fluoro. I went back to mono and no issues like with the fluoro. I chucked the fluoro for trout and will stick with mono. Between the extra cost and the lack of proof it makes a difference to trout I will stick with mono for trout fishing.

As Louis pointed, out there are issues when leaving any type of leader scrap on or along the stream. I recently picked up all kinds of plastic crap along my favorite stream and filled my vest back pouch in one outing, including beer cans. It is pathetic how some people treat our precious resources.

Glad to hear stories about folks packing out garbage. I keep a bucket in the garage for fishing line I've removed from stream banks, and when it's full I burn it all into a less dangerous mass.

How did you hook up with Elke? He is very much involved with the plight on native Americans.

Matt, my nephew found the Todd Moen video about fishing salmonflies on the Deschutes with him. I looked up Elke and asked if he had any days free to guide when I'd be heading to Oregon. He did, we booked, and he put us on fish all day for two days and suggested places to fish for when we weren't with him. I really liked him and his wife; they pretty much pointed us in the right direction and then left us alone--until it was time to move. We talked about everything when we were in transit, the environment, history, geology, you name it. We floated one day and went 4 wheeling the other, seeing a lot of the reservation. Starkly beautiful country.

the only difference I have ever seen is ditching fluoro completely has caused me to ride a little higher in the wallet...

Man, isn't that the truth. $4.95 for a spool of Rio nylon versus $14.95 for a spool of the Rio fluocarbon. I use about two spools of 5X and 6X fluorocarbon every year and one spool of 4X. Some of my friends use the Trouthunter fluorocarbon at $20.00 per spool which I think is insane. That is a $50 savings. A tank of gas and lunch.

After getting some new mono and hooking several 20+" trout all in one evening. I will definitely not try the fluoro 4x or 5x again. And I will save a lot of money too.

Matt, I agree with you, $20 for a spool is insane!
