IO Sets for Electric Melee

[Alverant]

My brute will reach lv50 soon and when he does, I plan on doing a respec. I'm looking for suggestions on which IO sets are best for this powerset and how many slots each one should have. Presently, I have all the powers but build up since that's not a type of power I don't use much. Same with Lightning Clap. For Taunt, I have the Chance for Disorient. Bio Armor is the secondary. I solo most of the time so I focus on survivng and dealing damage. Holds/Sleep are nice, but not key. Thanks in advance.
