Wait what.. are you talking about that specific variation (shown on your video) of a one-handed air flare or just the move one-handed air flare that only 10* bboys in the world are capable of doing? Cause I can tell you there’s more than 10 people in this world that can do a one handed air flare and no I’m not counting air flares like Bruce Almitghty. More so like RM, Pocket, Monkey King.. etc
You might know more powermovers than I do! I can’t personally think of more than 5 or 6 bboys that can consistently do a one-arm. Point is, it’s impressive
