I an new to this forum.... I fished western lake erie extensively in the 1970's and 1980's... I won several tournaments and placed hi in several more using downriggers and flat lines. we used "slider" rigs on our down riggers and usually ran lead core for flat lines. I have not fished the lake since the 90's, what has changed. Why has everybody gone to "boards" "divers" and other weighing systems.
