"Luna" minnow is a twitching minnow for trout and other smaller freshwater or saltwater species.

The fixed weight gives a stable position when twitching and creates a feeding posture that does not give a sense of discomfort from the fish so to strike by reaction. "Luna TR", which maintains a more minnow-like posture, is also good at slow retrieve  so you can enjoy a minnow like action to draw strike from the fish."
