I have access to professional swaging tools but have never replaced standing rigging on any Hobie with anything but OEM and even then I have had at least one failure. My fault for trusting a very slightly frayed wire at the swage. Lesson: spend the $$ and don't take chances or spend time dismasted and lonely.
Other lines and cordage however, I find that West Marine is a great place to look especially this time of year when they are looking to reduce inventory. I replaced my halyard for 32cents a foot with stuff that had been going for $1.25a foot. Good deal.
