It is very true you can get them much cheaper if your willing to make them yourself, but my personal preference is the Revenge jigs(tacklewarehouse now has them). Its got a good hook and head shape that gets through lots of crap.
Colors can be kept pretty simple black or brown as your base color for your jig is usually best. Then have fun with your trailer. My favorite is a black and blue jig with a piece of black and blue pork or plastic. Black and reds also work real well. If your going to use pork get Superpork, its much easier to use than unclejosh in my opinion. I like to use a beaver as a trailer, as well as the norie bug it's also a cool creature bait, I'm sure the new yammie kreature would be good as well. I really don't use the plastic pork chunks if I want that look I just use pork otherwise I'm using a creature bait or a double tail grub.
