Wow, what an amazing tree! Be careful, though! If the tree backbuds to much, Dan will have you removing all the growth!
Being a "traditionalist"
myself, I find the Japanese ethos of using the least amount of wire possible to do the job correctly a fascinating study in discipline. I used nothing but aluminum for years. When Boon told me to wire this Mendocino Cypress using copper, I spent the next 2 1/2 days sweating bullets. I used the excuse that aluminum is much easier, so he gave me a corkbark oak and some aluminum wire! So much for excuses...
One of the keys to wiring and unwiring is hand position. If you support the previous loop while turning the next one when wiring, or the next loop while unwiring, your branch should never move at all. Support the loop, and guide the wire around the branch with the forefinger of your dominant hand. The wire should bend without touching the branch, and only be "on" the branch as you prepare for the next loop.
Branches break, it happens to everyone. The key is to minimize it. So make your unwiring and exact reverse of what you do in wiring.
