John,

>>...mostly from Bweaver stock... About 30% of my hives have not been 
treated in 2+ years...

How did you treat the other 70% for varroa?  How many Weaver queens 
do you have and have any of those hives turned out *hot*?

I've had hives go 2-3 years w/o treatment followed by an epidemic of 
shrivelled wings.  I hope you continue to experience low mite loads.
