i use straight braid with no leader.let me explain why.after years of switching lines and keeping track of fish counts i have found that overall i don't think line visibilitymeans a dam thing.i've used flouro one year and my count went up.i was psyched.the next year i used it my count went down.i've used mono and tons of different brands of braids.i've fished next to guys with floro and the bite was tough and we both caught close to the same amount of fish.sometimes the flouro got more sometimes my braid did.my conclusion is it's all about putting your bait in front of a fish that wants it and has nothing to do with line visibility at all.since braid is without a doubt the most sensitive line out there i choose braid for all my fishing.i no longer worry if i have the right line because i know i do.
