I use the pre-tie sets for long-lining also......some lines out as far as 125 ft,
with the swivel ahead of hooks/jigs - you don't have a line twist, jigs also follow
more inline than tied idrectly to line.
Tangles just cut them away and tie on new double. also can quickly adjust
variation of jigs ( 2 - 32nd's) 1- 16th- 1-32nd) 2 - 16th's) 1-32 - 1/48th, 2-48th's)
combinations are much, much easier to snamp or tie on with pre-rig.

Use different set up for spider or tight lining.............. however, again do have
pre-sets made up for quick change outs..............
