I sure noticed the same thing in my operation this year, Bill, and I don't have any old, dark combs, nor have I used synthetic miticides for several years. I sell so many nucs that I have rapid comb turnover. I also don't have significant pesticide exposure. Yet bees still appear to do better on foundation, as opposed to drawn combs. I'm planning to experiment more along this line. BTW, great post Lloyd, although coumaphos has been detected several times in honey.
