Over the last year or two, I've been increasing my use of plastics generally. In December, I was on Lake of the Woods and caught crappie and a mess of perch on a small round head jig with an unscented twin tail grub...that was enough to sell me. It saves time since you aren't rebaiting all the time.
In a variety of situations, I've used unscented, PowerBait, Yum, and Gulp. One of the bigger problems I have, particularly in winter, is finding the smaller plastics. Give me a 1-2 inch grub, twister tail, or something like a mimic minnow and you can catch a lot of fish (my wife caught a 31" pike in open water in September using a small jig and twister tail), whereas, big plastics will limit the fish you can catch to an extent (i.e. can't catch the smaller fish as easily).
