Hi Birdsnest,
I always and have done for many, many years, use tapered leaders, for still waters I use a 15 ft tapered leader with a 3 ft G3 floro' tippet, for river I use a 6ft tapered leader, with a 2 ft G3 floro tippet, I never, ever change from this set up, I don't know if it is hinging, wobbling, sinking swimming, floating, flying or whatever, I do know this, it catches fish, and that is all I require of it, I fish for pleasure, haven't got the time or the inclination to think about what a dam leader does or doesn't do, just go out there and fish with whatever suits you Birdsnest, life isn't long enough to P*ss about, here today and gone tomorrow, you enjoy your fishing my friend, we're a long time dead...........

And all this, life after death, is a load of B*ll*cks
