How good is electrical blast?

[brasilgringo]

I put a proc'd out Short Circuit on my recent Elec/Cold corr and the idea was to use it (and its 20' range) to proc the Fury -RES on mobs before starting to blast (and to stack with -Sleet).  Put I'm not seeing the procs (-RES, plus 3 damage procs) proc as much as I'd have hoped.  Debating whether to switch it with a proc'd Tesla Cage just to have another decent single-target attack, even if the chain damage from Tesla is weaksauce.  Anyone have good recent experience with the 2?
