OK, heres the deal. I don't want to come off as having the "Do It All" lure, but these are highly versatile. You could actually use just one rod and one lure for just about any technique you have need for in a day. Obviously topwater is out of the question but just about any other method can be accomplished with the VibraShock.
You can use it like a spinnerbait,a crankbait or a jig. Slow roll it, burn it or however you like to retrieve it, its up to you and the fish to decide. Spring is an awesome time to use the VibraShock as well as any other time of the year. I'm not trying to say that this is the only lure you'll ever need, but it is something you'll want to have ready at all times. I personally love to fish topwater, but if I get a blow up and no hook-up, I'll toss one of these back in there and 9 out of ten I'll get that fish.
I'm going to let Jeremy fill you in on the rest, he gets to fish more often than myself with them and I know he has some tricks up his sleeve

Hope this helps
