Customize Engine Weight: Metal Ball
Rather poor balance due to tall height and ball tip
Tends to skip over the tornado ridge too easily, resulting in limited defensive ability
While a niche use, it does allow Gyro Engine Gear to self right quite effectively, making it an acceptable CEW for the part.
Despite being the heaviest regular CEW, Circle Defenser and Circle Survivor both weight more, and the latter is more useful in every way. In addition, only Circle Survivor can produce a Base + SG setup capable of rivalling the weight of Heavy Metal Core-compatible Weight Based Defense setups.
Overall, not a useful part.
