dark magic yoyo

I was told that dark magic yoyo is designed by world yo-yo contest judge Andre Boulay. It is his YoYoJam signature series that have been used by many players who became famous by placing as high as 2nd in the World Yo-Yo Contest and even 1st in the National YO-Yo Contest. You might fear that it is unstable because of its wide appearance but then this is not so since it does not suffer from stability issues because much of the weight in the weight rings is concentrated closer to its bearing.
