The pure vsh stock was pretty poor. Tough to keep the breeder queens 
without adding brood. The daughters were better. Now, with the carnixvsh 
crosses to select from and  vsh drones in all the yards, I'm seeing good 
patterns and less dwv. Your bees don't have to be pure vsh to have 
positive results. I believe Spivak says 25-30% is enough. I find overall 
my bees are productive with 100+ average in northern Vermont.
