Default Kevlar vs. wire for pull/pull retract steering setup

I need to use pull/pull on a retractable nose wheel. The servo is about 5 inches away from the nose wheel streering arms and it is a striaght shot. When the wheel retracts the line stackens. I used braided wire for pull/pull set ups first and it did not take well to being forced to bend about 90 degrees. So then I tried more flaccid kevlar line, which did accept the retraction action better, but still while under construction I notice the ends were becoming worn and only supporting a few strands at the threaded rod with a hole in it that attaches to the clevis at the servo. Have you had similar experiences - how do you prevent this or otherwise make wires work?

Also, I ran out of the supplied copper crimp tube so I used aluminum and then brass, neither seemed to work. I even added CA but the kevlar line still stackened on me. Maybe I am just not crimping it correctly. I did use the technique of threading the line back through twice in the crimp tube.

Thanks for any assistance you can offer.
