In any case, spinners should be attached to your line with a barrel swivel to prevent excessive line twist. Thin spoons wobble well with a slow retrieve, which makes them useful in early spring when cold water in streams makes browns sluggish. Thick spoons sink fast, cast far, and work best in fast, deep water. Medium spoons do everything in-between. Like spinners, they are simply cast and retrieved, but these spoons get to the bottom faster and can be retrieved slower, as there is no blade that has to be kept spinning.
Spoons are the number-one lures for trolling for brown trout in ponds, lakes, and some big rivers.
Medium and thick spoons can be trolled with little or no added weight in the spring when brown are fairly shallow. When the fish go deeper, spoons of all thicknesses are trolled with weight or with a deep-trolling device. You can dead-drift or bounce a jig along the bottom. Or work a jig, jig and minnow, or jigging spoon vertically at very specific depths in slow-moving rivers, lakes, and ponds. When trout are finicky, particularly in still water, it can often help to add a piece of a night crawler or a small minnow to a jig.
