I use 8lb line and pull single 1/16ths or double 1/16ths according on how deep the fish are
I mostly pull curly tails and color depends on the color of the water
Clear water light colors
Stained water darker colors
I’ll put out a mix of colors to start and let the fish tell me what they want
You don’t need livescope to catch fish if you have a good graph and know how to use it
Let me know if you need anymore help
I usually troll around 1.0 pulling jigs and a little slower if I’m pushing jigs so if you know you’re on crappie and not catching them you need to start changing colors or speed up or slow down
