I hear you and understand. My goal is to have a diversity of queens lines in the apiary so I have a diversity of drones available for breeding for normal re-queening via supersedure or emergency cells. Most of my yards overlap the flight range of my adjacent yards and I tend to understock yards to avoid excessive competition. I went to a bee meeting at Penn State 4-5 years ago and a friend of mine gave the results of a study he and his colleagues conducted and the number of hives that superseded after being re-queened was amazingly high--much higher than I would have guessed so it made me feel even better about my management stye. I have queens early in the season and nucs later in the season; both are good insurance policies to speed up the process because when I detect a problem, time is usually of the essence to get them back online as soon as possible. One of the downsides to having too many hives--just can't track them closely like a hobbyist or side-liner. That's why, on not-so-busy days, I just like to open a hive or two to enjoy watching bees being bees. For that reason, I plan to have bees till the bitter end, just fewer than now.
