What's the technique???

[GetANet]

I see alot of the trout guys using plugs like rapala's and pin minnows to catch some nice trout and was wondering how do you fish them? Cast upstream and crank it back down or downstream and work it back up? Do you use a steady retrieve or twitch it? Would like to try it next time i hit the stream and was hoping to gain a little knowledge to cut down on the learning curve a little. Also what size and colors are prefered Do the floaters or sinking ones work better? Share some love my brothers...............
