Why don't you rig your own....
I don't own a hobie,. but I don't see why 500lb + 316 stainless wire rope won't work with copper crimps.
Or go heavy....just make sure the stainless is 316 and not 304. When I had a steering wheel on my canoe I used home depot plastic coated wire rope with clamps and plastic pulleys never had one problem.
