Check 6's are helpfull, It's saved my rear a few times. I don't expect them, but they are nice to get. I return the favor as often as I can...It does bother me though when people get upset over not getting one. I've seen a guy with three cons on his tail I tried to give him a check, but I checked the wrong person(which happens too often for me) I figured he had to know they were, then boom...gone "thanks for the check!". I pretty much figure there is at least one on me at all times because of the big orange letters on my plane that say "kill me first", I have never gotten upset over a sudden blood filled end to my sortie, I just figure I need to be more aware.
