Hi Fred,

You provided me with the perfect question to chew on just when I sat down for a nice dinner and a beer (after a day of hard work).
Thank you for giving the opportunity to shoot off my mouth.

This question is similar to the one asking which is the best colour to wear for the Friday night party.
For my taste, the first and foremost criteria is the hight/nebari diameter ratio. It varies from species to species. For example, trident maple sould have at least 5:1, more like 4:1.
As soon as the desire taper is achieved, the runway is clear for take-off.
Exceptions are mature collected material with strong character. Here, the above ratio is preceded by trunk movement, bark, branch placement.

All the best,
Attila
