We're only humans, aren't we? No-one is perfect. As long as the fish think we are all is well.when I cast it is back and up or is it up and back? rather than just back ,It has taken me most of my life to become an over night success, and I can still make mistakes, but there you go, easker1
ThisAll I can say is I've no idea now what's being spoken about..
I'm also wondering whether hingeing is theorectical rather than real. Has anybody actually seen it or tested it?
It seems to me that the loop to loop connection is the only one where this could happen as the 'knot' joint can flex.
I completely disagree with your view on loop to loop You expressed it previously and I thought you'd missed out "not" or "no" by mistake . By having the doubled leader in the joint the transition from flyline to leader is made smoother and less likely to hinge (if there is such a thing).
Thanks that's the sort of thing I'm after - authoritative but also understandable. It also brings up the idea of hinging that I need to include.
It strikes me - without any evidence at all - that a loop to loop connection could be a better source of hinging than almost any other method.
Plus "It seems to me that the loop to loop connection is the only one where this could happen as the 'knot' joint can flex. " from a couple of postings ago.
Because in the parabolic test you are compressing the connection and I can't see how this would happen in casting, where it is stretched rather than compressed. Or perhaps I misunderstand your parabolic test.Ok. My reasoning is that the loop to loop connection is the only connection that could be loose enough to hinge. All the others are mechanically fixed. Whether this is actually a real life possibility is one of the questions I'm asking.
Additionally, the only two examples of hinging I've seen - using that parabolic test I spoke about above - was in loop to loop connection.
Why do you think this is wrong?

Therein lies the ''fit for purpose''analogy of this thread.Hinging occurs where the join between the fly line and the leader is inefficient. As Mark says, that may be as a result of a 'broken' joint, as in his example of the line covering cracking above the loop but more commonly the effect is caused by the difference in diameter and rigidity of the change from the fly line to the leader. Now, if you fish mainly with the wind behind you, you roll cast a team of flies over the front of a drifting boat for example, you'd have very little difficulty fishing with a level leader of say 4X, around 6lb breaking strain. However, if you were attempting to cast a large Mayfly upstream, facing a downstream breeze you'd soon discover that the leader would not extend and turn over as the energy transfer from the fly line to the 4X leader is insufficient - the cast collapses - the analogy would be along the lines of attempting to push a hair into play dough. Hence, the joint between fly line and leader needs to continue the taper of diameter/ rigidity/ density.
