Doing this now. Best way is:
Something in the Air x1
Wayward Wares x1
Bastion Op: Ward Warden I x2
level 2:
Hazy Prospects x1
Looking for Lookouts / Bastion Op: Ward Warden I mix/match until You hit level 3.
Edit: something to add; The two ward warden i did to increase my fame, I had filled the bag to max capacity by going down the list, and once i was about halfway, filling it only with round objects, as these seemed the least likely to break the bag. Returning a bag at less than full capacity may lower reputation gained from it, forcing you to do more Ops to rank up. I'm not certain about this, but It's a possibility.
