Just so you guys know, shotgun/pistole/power weapon run-and-gun kills don't count towards Veiled. Only pistol, AK and a few others do. I'm not even sure Uzi kills do.
Personally, I would just stick with Rapid Hands or whatever other booster you enjoy in that first slot. As of now, you're not going to be making much money off of BoHs. 10K, maybe.
With the new medals, it's getting easier to level up without BoHs. I'm almost at level 54 and I was about 5/8 of the way there before 1.05. I'd say you can make 100K in an hour without BoHs if you're good enough (in deathmatch, that is).
