Thanks for the information on your tree.
I was reading your post that you linked to and you said you were thinking of replacing the polyester straps with metal banding. I was wondering if that would cause some GFCI tripping? Do you think using metal bands will cause grounding issues? The reason I ask is that I have some metal trees that I put in the yard and when it rained, the GFCI would trip. So I drove some pvc piping into the ground and inserted the tree trunk into the pvc pipe (insulation against the ground) and my GFCI's stopped tripping. I understand I may be introducing some risk (as in getting shocked if I touch the tree, but the I generally don't run my show in the rain, and I realize the GFCI's are pretty sensitive to mA current drain, so I am okay with the risk.
Regardless, your show looks great and your tree is very impressive.
