Roger -
Are them there trouts naturals or planted? Are there even any native trout left in the world?
If you come to the SBSCBC, I will give you the best lake trout catcher in the world. It is a little old fly that you troll with 10 feet or so of 4 lbs. leader attached to your mainline. No weight, no worms, no spinner, no nothing else. Drag it slow way back behind the boat, and keep your eye on the V it cuts in the water. Very soon, there will be a big splash there. It is a simple tied back caddis, but you will never be able to duplicate its effectiveness unless you have some Clatsop County, Oregon, deer hair to use in making it.
