I usually use 2x or 3x tippet with about a leader length of five feet or so. What i do is keep all my old leaders when im done with them and cut them down short, add some 2 or 3x and use those as streamer leaders. i really need to tie some smaller buggers. I fish a lot of zonkers too, both white and black.
Gerry, do you mind me asking which tva section you were talking about. im familiar with the wier dam and the hickory tree bridge section, but i dont know squat about the area in between. from the info you gave, it kinda sounds like you were fishing the slow pool above the small island just upstream of hickory tree bridge? Big drop in temps last night might have warranted slower fishing today. just a guess. im headed to the SOHO tomorrow morning, i hope it picks up.
