Looking for tackle ideas for huge browns. I plan to fish the Missouri between Helena and Great Falls. Will be there around the fourth of July. It's artificials only. We will be in a drift boat. Have fished it in the past with success on rainbows and smaller browns using wolly buggers and panther martins. Might try pulling plugs. I know there is a good population of crawdads they feed on. Does anyone have any hot ideas they have used successfully?
