>Is the Double Back kick the best Defensive/Offensive move?
Yes. It's a hybrid Wing Chun + Taekwondo move. You can tell by the high level acrobatic skill required to perform the move well, along with the combination of defense and offense simultaneously.

>>1462378
No. The spear is.

if someone properly defends against it chances are you're going to land on your stomach or your back, whereas with normal kicks you'd have to mess the kick up entirely and fall all on your own, or get your leg grabbed, or get sweeped while trying to kick someone in the head in order to fall

furthermore if the first kick doesn't land due to them stepping backwards or sideways you're in an awkward position and might make the mistake of automatically trying to perform the second kick

i wouldn't recommend it

>>1462378
Its a good move, just make sure the first kick lands on the body or else you're fucked

>>1462378
that isn't a back kick, its a side kick followed up by a spinning side kick

if you didn't do karate you don't know how to do a back kick becuase nobody else teaches it. You are supposed to be standing 12 and 6 and kicking backwards like a mule

Does Korean Karate (TKD) count?
