I have been breeding Electrikes for days, and I have two final Electrikes with HP Ice (I think it is nice for coverage, since Manectric doesn't have a lot of moves):
(Calculations at level 20)

Timid
Hp: 10-14
At: 0-4
Defense:30-31
Sp At: 30-31
Sp Def: 30-31
Vel: 30-31

Modest:
Hp: 30-31
At: 0-4
Defense:10-14
Sp At: 30-31
Sp Def: 30-31
Vel: 30-31


Wich one do you prefer?

The question is: Hp or Defense?
And: Modest or Timid?

Thank you very much for the help.
