When trolling I prefer to use em. My thinking is to hit on every sense they have I can. I use Roadrunners for the vibration and flash of the blade, And then add either curl tails(Bobby Garland Stroll'R, Southern Pro Hot Grub, BPS Cajun Critter) or Sliders or Strike King Slabiliscous to get more thump on their lateral line. Does it matter?? But seems to work for me pretty good. I also add some Bobby Garland Slab Jam just cause. Thats my thinking and could be way off base.
