I would really appreciate the experience crappie/pan fishing to help me with a dedicated set up with the limitations of space and mobility of being a bank fisherman in mind.
I would go with a 6-7' light or ultralight rod, spinning reel and 2-3# line.
A lot of guys here like the JDM rods/reels/line. (You can read about them in the sticky threads above.) There are lots of other rod/reel options, though.
