compare sigma blade zwei and dark magic

witch is better for sleeping ???

That would mainly depend on your throw. Theoretically, the Sigma Blade Zwei with it’s narrow bronze rims which are slightly denser. However, it does not do much and I would recommend the Speeder as the alternative to the Sigma because the Sigma is mainly for 3a. Also, the Dark Magic is stabler than the Sigma or the Speeder. All you need to know is that the Dark Magic, Sigma Blade Zwei and the Speeder have as much sleep time as you need.

Also, the Sigma Blade and Speeder have a similar shape (V-Shape). The Dark Magic has a Rounded shape. Also, The Speeder and Dark Magic are hybrid response yoyos while the Sigma Blade Zwei is double o-ring.
