Hmm...yeah I guess I have a tendency to bunker down and get overrun quickly with collectors. Those seeker swarms make me crazy...I feel crippled when I can't reave that captain charging me.
Thanks for all the advice guys. I do love power kits, but I've become very fond of the salarian infiltrator with piranha, too. I kind of prefer him to the geth thanks to energy drain.
Move fast or die... at least since it's Gold, there won't be any engineers trying to surprise you with turrets. 
Glanced at your manifest. Since you mentioned your human engineer -- w/o burning any spec cards, have you considered something like

?
You haven't used the Wraith, I see; it's lightweight, on the accurate side for a shotgun, and has respectable damage.
- Geth Scanner III for awareness (15m wallhax, if the wiki is still correct)
- Adrenaline III, because movement can save you... probably more than the 500 extra shields if you use one of your few Cyclonic IIIs
- Drill Rounds, partly for 2.5m wallhax and partly to conserve your AP ammo
At +143% power recharge, your incinerate or overload cooldown is 2.98s; that's only .31s slower than w/ a Hurricane I. That's not likely to matter much at all.
If you expect to get up close and personal, the Piranha IX is almost as light as your Hurricane I and rather brutal. But the Wraith will let you pop Collector Captain heads or Scion sacks from further away more easily.
