@MT, your argument has merits. there probably is no definitive way to prove it either way so this debate will probably go on for a long time.

you made me think a bit about my reasoning, which is always a good thing, and then i started thinking about the stuff that i do subconsciously (crazy stuff, let me tell you)

when i considered which baits i use on the braid as opposed to which i use on the 4# mono i established a pattern that i never really consciously thought about. the baits i use on braid are all reaction based lures. (trolling plugs, jerk baits, spoons, spinner baits, large tube jigs). because these all are reaction trigger lures, the line matters less. when i use a slower finesse presentation, its always with mono. this goes for rubber worms, small jigs, live bait (where applicable). mono is for the kind of stuff that is slow and the fish tend to look over a bit more closely before they eat it.
