Here's an older article I wrote just after I started studying with Boon:

It contains some larger pics of developed collected trees and the wiring we did on them. The most important part of wiring secondary branches is "figure 3." Boon has a handout which diagrams any situation you might run up against in wiring collected trees, since they don't ramify smoothly like a trained deciduous tree should. Figure 3 shows the proper way to wire a "slingshot" type of branch, or any branch where you are wiring both sides of a fork with one wire.
You can find more discussion and better photos of Figure 3 solutions at
