Have you tried the Vanguard pulse rifle yet? (Vox something) I accidentally purchased it the other night in a drunken blur and I don't care for it at all so far.
I have not tried it yet. I would like to because it has very high impact. May be my next purchase once I get enough marks again. I just bought that vanguard fusion rifle a few days ago.
Edit: It's called the Super Pox PLO
