NanoFil is expensive. Are you surprised? A 150-yard spool starts at $19.95. The line will be available in 1-, 2-, 3-, 4-, 5-, 6-, 8-, 10-, and 12-pound tests. The 1-pound specs at an incredible .001" while the 12-pound specs at .008". The color is a milky white translucent, meaning not clear but not completely opaque either. I'm told it will start appearing on tackle-store shelves by mid-June.
