Length of line behind ball

So in the Sturgeon Bay area for salmon/rainbows in what I assume is fairly clear water what length of line do most people let out behind the ball for spoons/or flasher/flies. Been getting mixed messages on this from anywhere from 10 to 60 feet. I fish alot by myself so hard to learn except ask questions and read. Thanks !

"Lots of factors involved"...Some still use metal dodgers and flies instead of plastic paddles. I still like to keep the metal ones on a shorter drop back because longer leads seem to reduce the action with shock absorbing mono in front of them. The 100 rule sounds good for spoons, to me. Deep tangles with fly rigs are a pain. Thump is right about factors involved. You might try this thread in the Great Lakes section too.

Many guys use the "100" rule and it's pretty productive.   example: If fishing 40 down go back 60.   If 80 down go back 20...etc...     I use this method with good results on both spoons and FF combos.      

WHat I have been told the deeper your run the ball the shorter the length.  I wouldnt do under 25-30 feet though.  I try to run 30-40 at most depths.  

Lots of factors involved...depth of ball, number of riggers, stacking riggers, lure (F/F, meat or spoon), species targeted, other rods in the spread, time of day, etc.

With multiple riggers and stacking, your leads get somewhat determined by the set-up.

If you are fishing alone where a single rigger will be by itself, you have more freedom on lead length and just have to experiment.
