Seven should ride lane rails via electricity

[BigLuckBrian]

Enough of just using his hand like (most) everyone else. Seven possesses TRUE power, let him unleash it! He travels down the metal rails as a lightning ball like a current, perhaps making little lightning sparks around him as he goes if it isn't obvious enough to opponents.

basically none of them should be using their hands to be honest. They could all pull out a generic grip hook/meat hook/boning hook out of nowhere and it would be way more fitting.
But it would be really cool if each of them used something specific to their skills like you say, same way pocket already does.
