Most of the string wear we see in the cable guard area was due to shops or people not tuning the bow correctly. We have had several bows out of our shop now (very close to 40 ) including ones we have retuned from a certain internet company, and have not experienced any issues with string wear. My evolution is set up at 85lb draw and I don't have any wear, and its a 2014 model. If you guys have any questions feel free to come on by the shop.
