20 yrs. ago on Choctaw lake we long lined using old fly rods and Zebco 33 spooled with 6 lb. line . Make cast and pull for 100 yids . no fish ? let out line 5 ft. every 100 or so yids . Normal pass of the levee would make two adjustments . Your system will work for sure . I mention this because most any change or continued adjustment will work .
