Yes, Gonzo. What you say is so very true, & understandable. But, it is a pity that the "old tools" cannot be resurrected in these sort of circumstances.
Off on a tangent; I well remember the use of Climb & Descend VMC. This was a very useful tool when Radar was not available. We used it a lot at Aberdeen in the days before Radar (& even after Radar became available - when it failed for days on end !). Mostly worked a treat; although, I can remember one or two embarrassing events !
Climb/Descend a 1000 ft. above/below other traffic was very useful too; & even in a Radar environment, when pushed.
