Hi', Nidd. I hate to sound pessimistic, but in over 50 years of fly fishing I have tried all manner of connectors/connections and not one has been totally successful, as they all produce a crack in the outer coating of the fly line, where there is a step, up or down, in diameter.
The connector that permits the easiest and quickest attachment of a thick leader butt to the end of the fly line is the old plastic 'shuttle-type'. It will pass through most tip rings fairly easily, and its weight/bulk is minimal; but the fly line will crack, after a while, where the fly line enters the 'shuttle'. I am quite prepared to go back to using them, if I can find some.
Fly lines also crack where the coils of nail knots or needle knots bite into the plastic outer skin. Feeding the thick butt of a leader, if you can get one of the right diameter to match the end of the fly line, through the core and out of the skin will stress the skin also. We have to remember that perfect, or even good, transfer of power from line to leader demands the use of a leader butt that is at least 60% of the diameter of the end of the fly line. That is why I used a plastic 'shuttle' over thirty years ago, when I made knotted, tapered leaders which followed the formulae of the great Charles Ritz. I have never had turnover since those days to match that of Ritz leaders when they were connected with 'shuttles'.
Braided loops killed off the 'shuttles'; but they add a lot of bulk, at the loop-to-loop connections that many use, and they cause lines to crack. I am currently waiting to see if the last braided loop on my most recent purchase -- a 3wt DT floater --- behaves more kindly as I have dressed it with a coat of liquid vinyl which is tapered down the line above the sleeve on the braid.
I may even go back to stripping the skin off the line and making a loop with a tying silk whip. I used to do that with my salmon lines. They hinged a bit, but fished OK, as presentation was not as important as it is with dry fly for trout, for example. TC
