Interesting--I had a Camo TKL for a while, from ~2011, I think, and it was fine. I used the Camo cable in another Filco later, and also no problems. Good to know for reference.
P.S.: I always coil my unused cables into a loop, plus Filco cables have pretty handy velcro wraps on them for that. Bending in sharp angles is not very good for cables in the long run.
