I researched Amann and came across Serafil, I then found what sizes/colours were available in Australia and ordered from an importer here. You will probably have more access to colours/sizes than here. I found size 120 using 3 threads in a ropewalk produces a seizing size rope. You can then multiply from there. I then also have size 60, which I make rigging rope from 3 threads. From there, you can do the calculations as to what you need. I would recommend size 120 in black/dark brown, 120 in beige (for seizing and other small rigging) 60 in beige (for running rigging), 40 in black/dark brown (for standing rigging), it's up to you. Cheers.
