Why was Railgun chosen for the Sisters project and not Kakine Teitoku?


Misaka Mikoto "Railgun" was chosen for the Sisters project who cloned her. But
she's ranked #3 among the level 5 espers. Why wasnt rank #2 Kakine Teitoku
chosen instead, or even rank #1 Accelerator, in the case the original
objective of the project wasnt to turn Accelerator into a level 6?




if I remember correctly the electric powers allowed the clones to form "the
misaka network", so they can learn from the previous battles and get stronger
over time.
