Hi Ernie,
Nice thick trunk for that guy. If there are branches you don't like, I would say to get rid of them. I'm not an expert, but got one this spring, and it's the fastest growing thing I've seen. And in your climate, I imagine that it will do even better. I put a thread up on mine, and just updated it recently. They are a lot of fun!
If you choose to remove the larger branches, it will only make the trunk look thicker in comparison to the relative thickness of the branches. I think it will also have a more natural appearance.
Good pickup! I like the trunk a lot.
I've been to House of Bonsai just one time and dying to go back there and the other nurseries within area!
