More realistic machine gun tracers?

[Bpdslayer]

Hi, I have a suggestion. Has anyone here played battlefield bad company 2? Well it's a bloody realistic military fps shooter. After reading this thread, I went back to play battlefield, and noticed how realistic the tracers looked. The COD tracers looks ridiculously large by comparison. I wonder as well, with the crazy vibration of the guns on the mounting, whether the tracers should appear slightly more irregular in their trajectories?
