A perfectly head on guns cold merge at co-altitude would be fine as long as the contestants are shown to be at the agreed upon merge altitude from first showing icon until the actual merge itself.
so you think dueling is fly past each other...wing tip to wing tip and only after passing by do you maneuver?
that's what it sounds like....
I completely disagree with that.
dueling is about learning to kill someone at the soonest possible time without giving them a gun solution....IMO
and that's the way you should practice...MA flying is gang after gang after gang...learn to kill fast is the best way to fight the gang...unless of course you fly in the gang then it dont matter....you are not really looking to learn how to fight/kill.
