Nubnubbud's React driver offers an interesting option for bladers: to be in one of two places. This driver, when hard launched, will often rip around the arena, sticking to the tornado ridge, before dropping off of it, and suddenly shooting right toward the center. This allows beys to get at center-holding opponents without stalling.
