I hear you about thickening it up, and that is what I am doing by running the sacrifice branch out so long. I figure I can always grow it out more later, but if you don't put some effort into the design early, than you lose that potential. I think the progress is pretty good considering it is less than two years from a cutting. It has also been back budding like crazy (even more since the photo) while growing out one branch at a time. I think Dorothy showed/inspired the technique for growing out one branch at a time to/for me. I'm not sure if her rational for the technique is the same reason that I like it so much, but letting one branch run, I have found to let the plant thicken in a controlled manner while building energy, without letting the design get out of control or letting the growth get too far away from the trunk.
