Norway says it's not neccessary to clean their Fusion vanes, so I figured the same was true for the Zeon. I got a few shots with mine yesterday, and while they do steer the arrow very well, and give good groups, the "visibility" of them was far less than expected. I really can't see much reason to use them over any other vane as far as how easy they are to track. I'll stick with my regular Fusions and Blazers.
