This is a brand new product for Mack's Lure, and I can see some uses for a small troll like this. One of the advantages of this troll is that it is built with Mylar blades that significantly reduces the weight of a troll such as this. The other advantage of these ultra light blades is that they will turn at extremely slow speeds. This can be a distinct advantage when silvers are finicky and particularly for a slow presentation to walleye. These can used in combination with a range of products and rigs for trout, silvers and other species, and I would like to see how it performs with a walleye/nightcrawler rig of some kind. It looks like it could be overkill for walleye and maybe too heavy to work well with an additional lure pulled behind it, but I wouldn't make this conclusion without giving this a try. When trolling in the currents that you get on the Columbia this wouldn't be a problem. Lake fishing is another matter.
