These are my teacher's trees (Ofer Grunwald).
(His article is in the link above some ware...)
Both with fully mature needles and well ramified in 2-3 years.
The mature needles are assential to hormone control and should not be removed completely.
His method is basically pushing the trees to the limit for a short period of time and decandle twice a year for building the basic structure and once its there, a regular red pine work schedule is enough to get the resalts you see in these pictures.
I am getting a tree from him, in order to lern this method, and ill post it in a different thread.
