I use braid on all my rods, flouro leaders when fishing clear water. As an experiment one day, i had 10lb yellow pp on and decided to skip the leader. I was in absolute clear water fishing a flickshake, (finesse fishing) and nailed a nice bass. Im another believer that the fish is looking at the bait not the line.
Im still more confident with a leader though, and a big bonus is you save alot of money. I was spooling my reels every 3 weeks when i was using straight copoly/mono... Now i can get a few years out of a spool of braid, and months out of a spool of flouro for leaders...
