I've never had much luck with spinner baits either. I've caught a few fish on them, but find I have much better luck with a flashy lipless crankbait (rat'l trap).
I don't catch as many fish on jigs as I do on t-rigged plastics. However, jigs seem to catch better fish. I usually use a jig fairly close quarters and around woody structure. Tips: Learn to flip the jig with the opposite hand you retrieve with; this will help you feel bites on the fall and allow for quicker hooksets. I flip it in near structure, follow it down with the tip of my rod with a little slack in the line (enough to let it fall naturally but still be able to feel a strike). If I don't get a strike on the fall I shake it and bounce it a few times, then pull it out. I then flip around the same structure in a few different spots, then move on.
I don't like to cover a lot of water with a jig because they don't slip through cover as well as a plastic. I mostly do a vertical presentation with a jig and only fish them when I'm looking for a quality fish.
If you are not confident in a lure, force yourself to use it for an entire trip. Most likely you will catch at least a few fish on it and build some confidence in it.
