Baby's First Corruptor - DP/Cold

So I've never played a corruptor. But I'd like to! And I've never played a Dual Pistols, either; seems like a good opportunity to fix both of those problems, but I'd like some advice on my build. Here's the rationale for some of the decisions I've made:

* I want a build that's capable of soloing or teaming without a particular emphasis on either.

* Most of the sets I picked were for RP reasons; I'm looking for advice on making a good DP/Cold/Dark, not just a good corruptor.

* Hover is just there as a placeholder until I can swap it out for Fly in I21.

* As far as Epic pools go, I don't really think I need Dark Consumption, but I don't like Oppressive Gloom on my scrapper and I doubt I'll like it any more here.
