Favorite fluorocarbon I say and use is berkley vanish 15lb and berkley 100% and seaguar basic 101 15lb and I use it for swimbaits and swim jigs , I mainly use monofilament for most fishing applications but fluorocarbon excells in some areas and I use a double uniknot with my fluorocarbon and monofilament line as far as braid goes not a fan and never liked it and makes a cringy sound through my guides , it bothers me , I use vintage gear only so my abu's prefer monofilament finding a fluorocarbon that can cast is a win win on one of my 5 rigs
