I like the idea of Kekkai Genkai, but how many different ones would you have to add to make sure a lot of people don't have duplicates?

Name of KG: Rai-Fuu Cho

Description of KG: Rai = Lightning, Fuu = wing, Cho = Cord(string, yarn, etc...)
Essentially produces a very light string that can float through the wind that runs electricity though. Can be woven to create different things such as nets and can be attached to kunai to channel electricity through it. The string itself is light and can float through the air, so just letting a bunch of it float around can make it difficult for other shinobi to fight you.

Effects of KG:

If you touch a trap set with Rai-Fuu Cho you become electrified(paralyzed/stunned) and take damage.
