Depends on where you are fishing oand what kind of trout. If you are fishing stocker rainbows then power bait fished on the bottom works all over the nation. But if you are going for wild brooks, browns, cut's, etc.. you better take a more natural approach, such as worms, grasshoppers, enev minnows and sculpins on those big browns.

if your going after big breding browns comming up strem id say go out at night and use some softsheld crabs. most of the big brown feed at night and so do the crabs so a its a good meal for the browns. use a light sinker and give a gental pull every few minutes and for hooking them take some bread ties and pull off the plastic and wire the hook to the crabs so they can move freely.
