Sorry to hear about your cam problems. I had the same thing on my FC400, but caught it early enough it didn't so any real damage. I have well over 1000 shots on my FC400, and the cables are in fine shape. You just have to keep them very well waxed where they pass through the TRG system. I like a teflon based wax, or especially the new Bohning string conditioner. Only thing that shows up is a little wax buildup. The Bohning stuff is much slicker than any other wax I have seen. I just rub a little in every 150 shots or so.
