Firstly the shape and color has to be right for the water (depends on favourite prey). I use the Wooly worm in yellow with an orange tail and in green with a red tail sometimes I use the muddler minnow. As dry flies palmers in grey or black are fine. Nymphs in different shades of brown are very versatile.
My favorite spoons were the ABU Toby and the Heintz spoon. I do not use plastic lures anymore. I think that streamers are more robust, more effective and easier to store.
Flies and streamers are easier to use than spoons when you try to operate them in a wide range of speed.
