1/64 oz to 1/100 oz tube jigs concealed in 1" tubes are pretty deadly on crappie in the wood. Bluegills will hit this combo readily. I use a 5' HMG rod with a sensitive tip for vertical fishing. I lift the tube 6-12", letting the bait fall back slowly. Watch the line closely because if the line stops falling...set the hook. Hits are "mostly" once the bait settles. I jig within 2-3 seconds if no strike. 

If needed, open the hook gap lightly for better hooksets on crappie.
