Trolling the ship channel?

[MathGeek]

In our years in Ohio and Colorado, we developed some precision trolling techniques that are very effective on freshwater trout and walleye. Doing some fall cleaning today, I see a lot of gear that we have not really figured out how to use effectively in Louisiana. The basic idea is that we can control depth and distance from the boat and simultaneously troll 6-8 lines out at depths from 5-25 feet deep.

We simply adjust the depth to where we're marking fish (or bait) on the sonar and then switch over to the lures that are working. We experienced tremendous success with technique (6+ fish per hour) on trout in Colorado and Walleye in Lake Erie, as well as doing ok on bass in some freshwater reservoirs. We know folks get similar techniques to work well in Florida ship channels and deeper areas, but we're wondering if this might work in the Calcasieu ship channel.

Thoughts? Ideas? Experiences?
