jigs are fished the best with either a centerpin setup or a spinning setup, because they both provide a drag free drift. A good tip is to use split shot instead of pencil lead as weight, the split shot balances the line and cast out nicely where the pencil lead will create a helicopter type motion. Jigs are rock magnets so fish them about a foot off the bottom. Sizes will depend on water conditions, but i use anything from an 1/8th oz up to a 1/2 oz. My favourite colour by far is a pink in the back and black in the front, with pink and white coming after that in second place. I like kramer jigs alot, mainly because i have had alot of experience with them, the jigs are made really well, all of them hand tied, and all tied on gamakatsu hooks. I happen to talk to steve alot and i trust his products to produce fish. check his website out, his prices are great and he also sells AWSOME steelhead worms. Bent rod jigs are also very dependable and they fish well.
