The new Trilene Fluorocrbon line is the most invisible fluorocarbon line on the market.  It is the strongest fluorocarbon line with the least amount of memory. 

When I am sight fishing, I  now use 6, 8 and 10# Sensation.  The lines strength coupled with its  sensitivity  allows  me to feel the bite of the fish, but not worry about getting the bass out of the brush.
