I use artificial shapes a lot in live bait situations. Especially in agreement with Muskygary about the expense of live bait with pesky critters like perch, bluegill, goby, etc. Sometimes tough to fool mother nature - I really wish that all tournaments would go to Artificial Only.
Where artificial baits really shine is with a slow death hook - I will use a Gulp! Fry, Pinched Crawler, 2.5" Minnow or the best one yet - the Killer Crawler.
For single hook spinners - the 3" Gulp Minnow is deadly.
Re-Charging the baits by putting them back in the Alive! Solution or spraying them down works well too.
