Overwintering Techniques

[GaryH]

I’m in my second winter. I brought my first and only hive through last winter with a super on.
I sublimated that colony last winter with the super on
This winter I now have three hives; one double deep with insulation in the form of an old fleece stuffed in the pitched roof.
One BB with super on hefted heavy
And finally a caught swarm in a Langstroth (a fake flow hive present ) with eek containing fondant and uninsulated pitched roof. So all quite different trials.

I intended to sublimate to treat for varoa with OA will this make the national super frames unviable for honey next season?
