Lightweight downrigger weights' performance

Nothing new to add.  I’ve used the lake troller on Odell with 4lb ball and 125lb braid at 1.3-1.5 mph and was easily able to get down to 80ft. Bigwater pdl with the dr mounted behind me to my left and the arm angled toward the rudder.  I’ve recently moved it to the track in front and to my right with the arm out straight.  Trolled green Peter at 50ft.  Didn’t try deeper cause I was catching them at 50.
