Most of my fishing is wet fly's and like John I use a Fluorocarbon furled leader and tippet. I prefer Berkley "Transition Gold" 4 lb. test line as it has proven to be very fast sinking and a 7' leader lets me turn over a least 6' of tippet. However if you are using a strike indicator the fluorocarbon leader may sink it. Go with a thread or mono leader instead.
