Ok, This is my question:
What hairs besides tori/uke go with kung fu as in combo and which hairs dont?

I think they can all go together (not sure) and the just over lap

I was told though Kung fu and Spikey doesn't go
and I was going to buy, might end up buying and if not, just resell it :P

That's the combo I would use anyway

Doesnt it have something to do with how many parts each hair has? like tori hair would be 1 while spiky hair 5-6. I'm unsure about this but thats what i've heard.

id heard u can wear all hairs at once, they will just clip in together and will look ugly, but i would rather test it out and if u found out. post it and other people will know it then.
