You spend all this money on a decent setup to catch the fish of your dreams, and then on the final end on your leader where it all comes down to at a certain point, youll start using the smallest snap you can get Its an abosolutely NO go
The constant motion gets their attention and the frequent pauses convince them of two things: one, that the bait is dying, and therefore a viable target, and two, that if they dont strike, they will miss their window of opportunity for an easy meal
You might not need this, but Im paranoid and dont want to lose a fish, this way there should be no slipping of the knots are tight Make sure they both are good and tight, this is the biggest weak spot in this design, if this loop comes undone, no fishy
You can purchase them from Perkisas
Other times it may be too tangled and I have to cut the line
