Well, if you folks'll have me, I'm available for any Saturday slot, and Sunday before around 8 PM EST, due to a DnD campaign taking place.

You could try installing a custom fire or medibeam model, that may fix it. The two I found that work best are these, from FPSBanana: Medibeam: http://www.fpsbanana.com/sprites/1829 Fire: http://www.fpsbanana.com/sprites/2502 Hope that helps!
