Westin Micro Bait Fidusen Slim (Black Yellow Clown) The Fidusen Slim is the perfect micro bait for all fishing situations! Compared to the previous version, it is slimmer and slightly heavier, which allows for more casts. The lure has an excellent attracting effect in the water and can be fished in both the upper and lower water column. Ideal for spot fishing as it sinks quickly and can also attract selective trout due to its smaller size. Weight: 3 g.
