Hey Rob, lots of interesting points there. I think I can expand on the fluorocarbon line thing. It is not invisible in water(as so often advertised), it refracts light at the same intensity as water. Basically you won't have an underwater mirror of light reflecting off your line, or a transfused core of light running down your line from the waters' surface. Color has little to do with this as it is all about the refractive index. The lack of memory and lack of stretch is what has sold me on the FC for my down baits though, I think fish sensitivity to line size has more to do with the increased mobility of lures(with lighter line) than actual bass vision of line diameter. At least that's what Pat Donoho told me one day while we were on Mead, and I've decided it makes more sense to me to think about line that way. When you get down to the fractions of a Milimeter, how does 6 lb. really become less conspicous to bass than 12 lb?

Saltwater fishing seems the same, lighter line with smaller pinheads to give them the mobility to swim into the chumline on a picky bite, but when the fish come to the boat, any line gets bit.
