One small point:
RG, you mention not seeing the other guy's tracers.
Tracers are an option, default is "ON"; but it's up to you. Some swear it helps (I think it does), others, more sure of their marksmanship, leave them off hoping for a bigger "surprise bounce". I must admit seeing tracers come over the canopy has kept me alive for another 4/345 of a sec on occasion.....
