I was testing out the two tracer mods, and I think the pistolfied one works a bit better (for me at least)
The blastcore one only seems to add tracers to vehicle weapons, and possibly increase IR tracer counts. The pistolfied one adds tracers to all weapons, and I have been using it on the server, really useful and visible, even during the day.
This might be because my PC can't reliably run blastcore though, so if that works for you, keep it, but I will point anyone with merely mortal computers towards pistolfied.
Also, the shactac squad radar is FANTASTIC.
