Charles,What are your plans for the three branches. You are going to need an apex. Are you going to wire all of the sub-branches out? When do you plan to pot the tree?
First I have to be sure it will survive. Concernoing the apex, I'm not confined to conventional design here. The tree is for my pleasure, not the pleasure of the community at this time. I may even reduce it to two branches in time. Not sure yet.
