I use tiny unweighted spoons to fish for pinks, and to avoid losing lures I like to run a dropper weight and a 3-way swivel (T-shaped). I use a 5-6 foot leader to give the lure the most freedom to flutter, and then 1-1.5 feet of line from the swivel to a chunk of hollow pencil lead, which I crimp on the end of the line (it helps to put a knot in the weight end of the line so the lead doesn't come off too easily). I use this setup in slow moving sections of river near the tidal zone that often have unseen logs and other snags. The dropper weight also prevents twisting in the mainline.
BTW - lure size often has very little to do with the size of fish you will catch. I have seen large coho hit a size zero Dick Nite spoon, and salmon and trout fry hit lures half their size or more.
