I just bring a couple of Wolfpacks for when you need them in an emergency, EG only one extract left, 4 minutes on the timer and a rocketeer over the exit, that kinda thing.
Wolfpacks are cheap as chips to make.
You only need three things really (5 potentially, explained) but oil, crude explosive, and arc alloy.
The make the Wolfpack you need an Arc Motion cores and explosive compound.
However Arc Motion cores can be crafted from 8 Arc alloy, explosive compound is crafted from 2 x oil, 2 x crude explosive.
So, if you run the Dam, depending on which end you start, go between water treatment control, though primary facility and power generation complex on the other side (or visa versa depending on which end you start), fight all the pops and fireballs along the way, there is your Arc alloy, the pops drop crude explosives, and you can recycle the pop triggers to crude explosives. That is already 2 out of the 3 things in plentiful quantities.
Then search through all the metal crates, and breachable stuff, particularly in the primary facility area, and you can easily get 30 x oil per run, often more. Dont forget plenty of stuff recycles into oil, the big gas cans, polluted air filters, motors, water pumps etc to name a few. Also (I think this may be dependent on a skill) but sometimes you get oil from breaching itself.
As a bonus sometimes you might find already made explosive compound/arc motions cores along the way anyway.
I can easily get enough resources to build 5-6 Wolfpacks PER RUN, doing this. On that basis there is no reason not to use Wolfpacks as a convenience when needed.
