Not sure how you're set up for the walleye, but generally most people trolling are going to be using jigs or minnows for crappie (longlining, spider rigging, etc). 1/32 or 1/16 (or combos in that range). Some use planer boards. Generally most rods for trolling jigs are UL. Some do troll crankbaits with heavier rods, but not sure if that's too early in the season (not my lake - I'm up in Knoxville - and I haven't gotten heavy into trolling CB yet - I know it's popular in the summer). A lot of guys single pole, too, jigging structure, casting, etc. Sounds like you were wanting to troll though. Hope this helps.
