I jumped on the RC bandwagon as soon as it came out, and all of my prints from then are just the same now as they were then. My advice would be to not develop longer than specs say use fresh fix and don't fix overly long, and wash at least twice as long as recommended, but not more than that. Any problems I had along the way came from getting sloppy in those three categories, and showed up nearly immediately.
When I followed the rules, which I did at the beginning when I was paying more attention, no problems developed. The most irritating problem I had was curled edges from too much wet time during a period where I was storing everything in a water bath and washing all the prints together every couple of hours during the day.
