bru, you could fill a library with all the theories on bait so learn as many ways as you can and try them in different conditions until you find what works when. getting a good run of fish is like creating the perfect recipe, there are many many variables to consider and each one will give you a different result. bait is only one aspect, putting that bait in the right spot is another. water conditions, temperature and colour all count. then there is the moon, tidal fluctuations, barometer readings etc...and to add to that, the weather from the few days before you go fishing count too...oh, the impending weather for the next day counts as well! getting the picture? here's a simple thing that the old salts used to swear by. get a little diary and every single time you go fishing write down all of the variables mentioned above that you encounter as well as what you catch. over time you will see patterns developing and that will increase your odds of being able to do the right thing at the right time.
