Do they make the wires onsite, or get them somewhere else?
don't know for sure
Is the quality as good as factory wires (or better)?
IMO, nothing beats Hobie quality
Are they single or double swedged?
don't recall. Also, don't understand why anyone would double swage, seems as though if wire breaks at either swage you're toast. Anyone want to explain why it's "better"?
Are Salty Dog's wires heavier?
go back and look at the link, they offer HD (heavy duty) sets
