Here's a link to a thread a little further down the page where we discussed the merits of Elec/Elec vs. Elec/Energy. My main toon is an Elec/Elec/Mu Dominator and I wrote a long post detailing my playstyle towards the beginning of that thread. If you have any further questions or want me to post my (expensive) build, post in either this thread or the linked thread as I check the Dom forums quite frequently.
