Honestly, i dont think it matters to the fish either way. I Tie my flouro to a tiny very good quality chain swivel,with a regular cinch knot. i tie the Braid to the other eye on the chain swivel with a palomar knot.
I give myself about 18 inches of flouro, and tie a snap, not a snap swivel, to the end of my leader, useing a cinch knot again.
I always use snaps, and no one can convince me that tieing direct to lures catches more fish.Fish dont give a dang how your lure is attached to your line, and i have produced as many if not more fish than the people i fish with, who tie direct.I use the smallest terminal tackle that i can get away with, for the fish i am targeting.
Always lubricate flouro.It tends to heat up slightly as it pulls across itself during the tightening of the knot.
