You got a ton of good advice already, but figured throwing this in there might offer some incremental help. Early last year I made a post about getting better at fishing swim jigs. That thread was just awesome with all the info and tips guys suggested for me in that one. Here's a link to it.
Then, almost exactly a year later, there was this thread that also had an absolute ton of good information in it.
Maybe you can get some helpful stuff from there!
