I think I will keep the branch for now, I have been toying with removing it, but something keeps pulling me back when I get ready to chop. The roots are OK for its age, but not spectacular, I plan to repot it higher this spring. Waiting to see where buds form, then I will give it a trim to make it more compact. Gumpo is not the best Satsuki for bonsai, lots of leggy upright growth, but are worth the challenge if you are willing to try.
Thanks for the comments,
