If all goes well this year and I can get my head around the design process, then I will probably consider converting my 8 channel [8 strings] roof tree to a spiral tree. That is if 8 strings is enough too.
I may need to call on your professional expertise to assist with the design of it, but that's only if I decide that it's easy enough for me to achieve lol
For those, such as myself, that are interested in the 'Spiral Tree', I found this 'How To Video'. It may help you in the designing of your own spiral tree.
