Once a year, if you cut out the "curly" section of wire (1st 8 feet or so) and re-terminate, it keeps the potential for kinks/frays down....
My experience is that it's not that big a PITA to look for an alternative to wire......
For 2016, I'm hoping to run 4 wire divers on Erie for walleyes..... our wires were so successful last year. This may cause other headaches..... I'll let you know.
