Sorry I neglected to mention a key parameter.
The problem with using BB+jobe in "pvm" while levelling is that ely hecks, ado hecks and all mobs you'll generally be fighting with exception of aliens will have enough AC's to make the BB damage feel extremely sluggish.
Basically, if your intent was to do good dmg by using BB+Jobe.... you needed to use them at level 60-75, not level 100-150+
If you want good damage while levelling, get an SPB. Period.
There's nothing else worth considering in all honesty. Early on, say, around 50-60 or so you could have used a tiig blaster but that's totally obsolete by 100 as well.
Soldiers live and die on damage, specials, add dmg and being able to kill their foe before they are killed, so trust me when I say this, you'll want a big damage weapon.
The only option that's remotely feasible, but I really only can see this being effective if you're levelling with a solid set of 150CC armour that you can update with 225ish CC at 150, is using a Jobe pistol+KMP 5

Now, if you HAVE some CC, and you want to twink up a bit, you can actually do some pretty decent damage with a JPPGP+KMP5, especially if you load up on energy damage.
However, it's probably more expensive than you really want to shell out for just for levelling.
My recommendation is hunt around for the parts for a SPB.
