The crossing of the kevlar should not pose a problem
due to "rubbing". The area where the cables cross present
only minimal friction if any at all. It is reasonable to have concern
at friction points on any kind of cable due to the possibility of
failure. I have experienced such a failure and lost a DP(cermark)
Pitts S-2. The supplied SS cable failed on the elevator where
the cable threaded through a Dubro threaded coupler.
