I use a 4'6" or 5' rod, 4lb hi viz line and 1/32 or lighter jigs, panfish assasins or similar body style will skip a bit more to get further back into the dark corners, etc. I do use jigs with hair at times, usually 1/32 or smaller, depends on what works. It's trial and error just like any other attempt to catching crappie. Older docks are better (less chemicals from the wood) deeper water is usually better, watch the line for movement. I practice by opening the OH garage door about 6-12" and then skipping it thru that opening or shooting it thru, and aim for a 5 gal bucket as well. I use a weighted float for practice, but when using a jig, don't hold the jig by the hook, only by the head
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
