You talking about one pole vertical jigging ??
If so, I'd recommend a 10-12' rod ... something along the lines of a Sam Heaton, Norsemen Outdoors ESP, or Huckabee rod. You'd want a sensitive tip (ie - fast action tip) with good backbone, yet light enough that you can hold it & fish with it for a good while without wearing yourself out. Balanced with a decent spinning reel, and you should be good to go.
Just stay away from fiberglass rods, or graphite rods that have a parabolic bend, and you should have a decent outfit that will serve you well & last you for many years to come.
