I don't think Phase Salvagers pull their weight in this. I'd add more Fractals and use them on Ball Lightnings, cutting out the Salvagers.
^ This. Also, 2 Phase Shields is not enough to properly stall, as you don't have a stable offense. I'd say:
+ 2 Phase Shield
+ 2 Fractal
- 6 Phase Salvager
Thunderbolts are nice, though cutting their number down to 4
might help speed things up more.
