We all have favorites for different reasons, and some just work better. Black/chartreuse ,blue/chart, pink/chart (electric chicken), blue/white, popsicle (pink/purple/chart), white/chart(acid rain), red/white and the reverse, and of course all of the solid colors. These are colors I use for trolling and I usually use curl tails.
For casting I like a lot of different colors above a silver or pearl belly Bobby Garland Baby Shad (BGBS)always have a place on my line up. Black over chart is also a standard. Solid colors also have a place here, and don't forget solid black and clear with glitter. Some days they just work.
