I have used 4 to 6 ft fluorocarbon tippets on my 5ft furled leader for the last year or so. I find that when I am fishing a dry fly the tippet invariably floats if it is untreated.(I have used Rio and Riverge fluoro and they both seem to want to float.) This is not in line with conventional wisdom -which is that fluoro is more dense than water?? The floating tippet is very evident when fishing small still water. Having the tippet floating in the surface film will, I would think, nullify the benefit of fluorocarbon in that the line is very visible as a "crack in the mirror" of the surface film
I was wondering if other dry fly fishers have had similar experiences with fluoro and what you do to ensure that the fly still floats while the tippet sinks below the surface film.

In lighter weights most leader material has a hard job breaking through the Miniscus.Just a fact sent to try us.

Yep, 10lb fluro sinks like a stone, 3lb, erm doesn't, for the reason jim says. Can't really see any point in using it in lighter strains for dry fly, especially as its not very environmentally friendly.

Trouble with fluoro (besides being environmentally unfriendly) when treated to sink for dry flies, it pulls the fly under with it as it sinks. Treating the fly to float means getting floatant on the fluoro which then stops it sinking and spooking the fish. You can get things right but tend to spend more time messing with leader and flies rather than actually fishing.

Drennan sub surface degreased with fairy liquid and ground cat litter does it for me.
Treating the flies pre season and leaving the box on a radiator also helps
saves that nasty film coming off in the water.

Once I used a fullingmill tapered fluorocarbon leader and found that the thicker end sank too much and caught on the river bed and the thin section floated, very annoying.

I've been through the flourocarbon stage over the past couple of years but found the 4lb and 5lb lines just as hard to sink as conventional mono. I now use fullers earth and washing up liquid mix every few casts on lureflash mono which is soooo much cheaper and can take knots easier.
