The more vigorous one that was topped is now 15" the smaller one is half that size. I was going to not top the slower one but in the end I did top at d20 and I also removed the top two huge fan leaves as a bit of an experiment. Should make for a very crowded top. Snapped a couple of branches one nearly clean off. I can report from the future that I left them alone for a while and they completely healed.
