my new set up, since 2013 for crap ditch runs. float on mainline go to a snap (just snap) to a swivel to bait. now how do i change beads you ask. i have about 20 pre tired beads on leader. all i do is takes off the swivel and the new leader with swivel replaces it. you only need max 5 swivels for 5 colours. or X amount for X amount of colours you pre tied and reuse it till, either hook snaps, leader snaps, and that is how i quick change on the water if i have to.
what is the reason for the snap you ask? it is to bust a lure on a go if i have to, because kwikfish and spinners saved my day that i would be skunked on float gear. i dont take two rods on the weekends for obvious reasons.
i dont beleive in under sizing everything to catch more fish. even on slow days. i believe in presentation, colouring, actual bait matters more. small weights and swivels wont catch you any more fish.
from what i understood, fluorocarbon is invisible. so i would assume all diameters are invisible.
