The majority of lake fishing for trout is done with a floating line, intermediate or a midge tip, which is a floating line with an intermediate tip. These lines are used when the trout are feeding on insects or daphnia in lakes.

When the heavy sinking lines are effective are when the trout are freshly stocked and the use of small streamers is the number one technique. They were made for what's called pulling flies. This is where you need the flies to stay down in the water column while moving them fast. You would be unable to do this with a floating or intermediate line.
