Eric - check out the link to AJs bait and tackle. A DB (smelt) is one type of small flutter spoon people are using out on the lakes. Most people use nothing much more than about 3" long and troll at slow speeds from less than 1 mph to 2.5 mph, which is why you need such small spoons to provide good action. Top guns, Smelt guns, Mooselooks, Sutton 61s are others. Get a NH guide DB smelt or top gun and a couple others. Get advice from Alan at AJs on other lures and how to fish them and you've got a shot.
It looks like AJs bait and tackle is offering his own versions of both the DB smelt ("smelt Gun") and now the Sutton 61 as well ("61 gun"). Also, I finally measured most of my top guns and Mooselooks and they are only in the 2 3/8 size range. Small lures for big fish!
