1. I use a setup like that for wacky rigs and dropshot
2. I use that for my t-rigs and jigs
3. I would use that for spinnerbaits
For my t-rigs and jigs, I use Seaguar InvisX Fluorocarbon in 10lb test, love it. For my wacky rig and dropshot, I have one spool of fireline braid for wacky rigs and a spool of trilene xt for my dropshot. For my crankbaits, I use Yo-Zuri Hybrid, I love it too.
