Now we have a discussion. Now I'll rattle back. Always do your homework when buying a bow. Most bows today use factory lubed and sealed bearings in the cam so no lube is needed for the bearings themselves. It does pay to spray some silicon into the axle periodically just to chase any moisture away, especially if the bow has been in the rain.
I, too, have had strings on a bow a long time. As many as eight years at which time they did show normal signs of wear. I'll stick by my theory that most people wax strings way too often. I've got strings that show no fuzziness even after not being waxed in a year. It's more a matter of how much care taken with the equipment. When not in use my bows are in a SKB soft case with nothing else in that compartment to rub the bow or any part of it.
I can't argue what is said about factory recommendations because I haven't read anything yet. I guess I'll just have to get on www.bcyfibers.com
or Brownell's website and see what they have to say. This would be much better than reading about opinions from people like yourself or me. They make the string material so they ought to know. Another good source might be some of the custom string makers on Archery Talk.
