I don't normally use bait anymore, but the few times a year I do (usally opening day when fishing with kids), I try different things. What was hot for us last year fishing just after midnight was slow tolling small jigs with tips of work or coated in powerbait. I started out doing this and the other 2 were trying rapalas and pop gear. After I quickly started out fishing them, they all swithed to this technique. We tried it another time with no bait or scent - just slow trolling the jigs and applying some slight jigging motion and did almost as well.
