Timothy,
This is very simple idea, and I dont know how many colonies you have, but I
would certainly try,say, 3 groups of queens from 3 different stocks.
You could see if you saw any major differences in survivability. Keep all
progeny in separate groups also. I highly recommend that one of the stocks
be one touted to have shown resistance to both tracheal and varroa.
