No tracers is the best way to go.
Almost everyone in the MA looks back and sees a d500 plane manouvering on his 6 but not tracers, so they try to keep their speed up or extend.. and that means flying straight or without much jinking.... and if you got plenty ammo (P-38!) you can get some nice kills which basically put themselves on the silver platter.
Plus it helps when the other guy really didnt see you sneak below him and missed!
