Okay, here's my story on downrigger balls. A couple of years ago at the Gorge, I was on a friends boat that had 4 chrome sharks. All rods were catching fish. In the midst of the trip we lost one of the sharks and had to replace it with a black ball with tape. That rigger seemed to die on the catch rate from that point. That is until I decided to add a ball troll to it. Then it caught fire and was hotter than the sharks for a good stretch of time. Take from that what you may but my opinion would be that stealthy balls aren't desireable for Kokes.
