its been my experience that the color of line does not mean jack when it comes to crappie fishing
case in point, in the smithville lake thread i started there were two guys who were just killing the crappie that day, more so than the other 4.
one guy was using SUFFIX high vis, the other was using POWERPRO red....the color mattered not
we tend to stick to the same spot down at LOZ, right off our dock. I use 10lb test/2lb diameter POWERPRO red, with a 1/16oz unpainted jighead with a slabbuster to start. Will switch colors, and also jigheads until they strike. I also use 1/8oz roadrunners, berkley gulp alive (the only thing they would bite on this winter/early spring), assorted jerk baits, shallow and deep diving cranks, and suspending rogues. The slabbuster/rocky top provide a good light action approach, if the fish want action the road runner equipped with a triple tip grub will do the trick! Also some of the suspeding crank rogue types come equipped with metal inside them that create a vibration after you jerk the bait, it will vibrate and suspend at the depth you jerk it to....the fish cant help themselves sometimes.
when in doubt toss a minnow, you are bound to hook up to something, and sometimes that is all that counts!
