American national distributor of fishing, hunting and other tackle Cabela’s is offering Colorado spinner blades with large holes punched in their tail parts, under the trade mark Vib-Orado. There are controversies in respect of this innovation. Some American anglers say that spinners and other lures equipped with the Cabela’s Vib-Orado blades are better than usuals, especially when fishing for walleye, Stizostedion vitreum, while others see no differences.

In our field experiments, we tested spinners with the intact and perforated blades in the foregoing manner.

Mepps Aglia spinners #2, 4,5 gr with the perforated and blank glo white blades were used in these experiments. In some lures, marked AP, 6 mm diameter holes were ideally cut in the tail parts of the blades (Fig.1). In the other lures, marked AB, 6 mm grey spots were glued instead of holes on the convex side of the blades.

Lures were tested in the evening twilight and night when fishing for zander, Stizostedion lucioperca, in the same manner that was described previously for zander and sabrefish:

In final sum, we found no reliable evidence that zander prefer spinners with the perforated blades (Student’s t-test). Note, under the daylight, fish could visually percieve the hole in the blade as an attractive flashing spot in comparison with the blank blade.
