I don't think it would be skimping. Each conductor (I believe) is 22 gauge copper. The shield is really excellent, and tightly braided.
And, as far as I understand, there's no reason to have more than 5 conductors anyway. Canare Star quad is really well made stuff. There are two versions, however. I would get the thicker version.
Anyway, I've used the gotham cable as well. It's fine, but I still think I'll use Star Quad for this project.
