Re: Synthetic cable over Nylatron Sheave

high end yatch hardware is probably about as good as you're going to
get--and some of their pulleys operates in the general force range you're
describing.

Given that it's a central issue on racing boats, and that they have
essentially unlimited budgets, I'd imagine that the America's Cup folks have
pushed this problem about as far as it will go.
