Pace/ 3G
What I mean is both systems do work. OHJ do need a bit more thought. I like the 45 join best but sometimes OH just works better. Thanks for the zillions of hours comment, but that makes me no more unlikely to screw up. It just means that I will be able to work out quicker how I have screwed up
Pace your biggest problem is that you put ATC into the equation, now there I would struggle to put my argument. Just leave OHJ to pilots it works out much better that way.
3G I like the Euro, but also like pre war non radio aircraft. It means that there is no mutual exclusivity to new and old ideas. Bit like Overhead and 45 degree joins really.
