Fly Jerk Machines?...video

[Jetdrive]

I saw two boats with these at MC the other morning. From what I could see the fishing was just as slow for me as it was for them. I was trolling plugs and spoons while jigging bucktails by hand. I did manage a legal brown along with some stockers.

As for those machines. I see a crowded reservoirs full of boats pulling extreme lengths of copper wire getting in each others way. Effective or not, at what point does it become overkill? Thoughts?
