Cool, about the line and the line size. My 62 y.o. eyes have a difficult seeing the smaller 2.5 line, no matter what color. But pink or orange or chartreuse is ok above 3.0 when conditions are good. Otherwise a thicker line. I played round back in the spring with a yellow braided line. The light stuff cast about like size 3, but is more visible to me than the orange or pink against dry brown leaves on the ground in early spring.
The previous post of sizes 3, 3.5, 4 as favorites was based on the TB line page. 3.0 for 5:5 and most 6:4 rods. 3.5 for most everything else. 4.0 for beginners and windy days. I suspected from recent trip reports that your opinion may have changed.
