I think you have opened up Pandora's Box and created a new Frankenstein. My bet is that this will be the longest thread in Beesource history.
Back to the topic.....
I'm not a professional beekeeper, have never had more than 25 hives, but I've been at this for a while. Kept bees in the late 70's (pre-Varroa Mite) and still keeping bees now in the present "Varroa" era. Based on my own personal experiences, and what I've gleaned from other beekeepers accounts around the country, I'm convinced that Treatment/TF success is largely dependent upon "regional" conditions.
If an area is not saturated with genetics that demonstrate varroa resistance, good luck going treatment free. I went down the TF path some years back, prompted by my desire to raise my bees in the most natural conditions as possible. Tried to do everything right. Small Cell, bought Hygenic mite resistant queens, used clean chemical free comb, no treatments. Still, lost almost all my hives to mite pressure.
I believe there are some segments of the country where successful TF beekeeping is possible. But where my bees reside, it's a losing proposition. Beekeepers need to understand their surroundings, and do what is necessary to keep their bees healthy and thriving. To this end I now use the most effective treatments available with the least amount of negative side effects on the bees health. If you are in an area where TF is possible, go for it.
My 2 cents.
