I use a 8 foot floro leader swiveled on both ends. When the water is clear I do believe it makes a difference. I have tested this theory out using 12 poles in the past. Also Dont use anything less that 20 pound leader if you decided to go that way. I learned my lesson several springs ago catching these big fish Ohio's. Also using a leader will allow the line to break if you happen to get to close to a reef, you know when your troll ing and boats won't move for you and you get forced in Lol.
