Try this:
A stiff 5" fluro hook link to a knotless knot, with shrink tube on the hook( make sure the tube is cut off at an angle in a direct line to the hook point) and is only fixed opposite the point on the shank, and for the swivel, I do a double overhand knot passing the swivel though the loops twice to form the loop, this nails them every time and you will land 99%
Tip: You can prepare shrink tube at home, just by tying a normal hook as a pattern, and then shape the tube over steam: 1 easier and the plastic will set, and 2 you can reuse with no worry about over heating your rig
