AFAIK the SFV is a bx and not the clone. It makes sense as the Chem 91 would be the female. So different males of same cross. It's been a while since I've researched this though.
I can tell you from personal experience, that the Double Krush is an absolute winner throwing down some serious Chem 91 fire.
