The power of jig fishing is in details. It's not like fishing just about every other technique where your primary goal is just puting your junk in front of the fish. Your goal is to harness the most complete and majestic natural presentation. It's all in the finesse! Some people get it right away, some people will have fished for steelhead for years and still need a guide to catch one on a jig.

Read some books.

My setup-

small dink in shallow/froggy water, sliding float in deep/turbulant water (don't worry about reeling up bobber stops, a rod long enough to fish jigs will solve that problem)

Weight that coorelates with the float schematics. I'm a new fan of jig weights.

Use the smallest terminal gear that the conditions allow

Make sure main line floats (I use mono with floatant, thread line is a great place to start)

waste a ton of money on fancy flourocarbin leader material (I use seagaur) in 8 and 10 lb

Try and get your jig to float through the water as if it were neutrally boyant and nothing was attached to it.

Don't put bait on it

Good luck, and you know when you'll have got it down because you'll be hooking more fish than everyone else.
