I have rather the opposite view to the more voluble forum users here.
Don't use Buckfasts, etc:

That article about aggressiveness is totally drawn from sleave.
Honey bee is aggressive, because it defends its colony, brood and food stores.
In nature it is very good feature. it is must.
Non aggressive is a feature of human selection. It is based on gene error.
In crossings the gene error will be often healed and natural original features come out.
Practically selection of bees stárted when people started to use movable frames 100-150 years ago. Then they could shange the queen.
"Aggression seems to peak in the F2 generation and then fade rapidly away, probably because the imported genes are rapidly de-selected by local environmental pressures (and beekeepers)."
who can count what generation is going.
in F2 generation only 1/4 original genes are left and then Carniolan is not any more 25% Carniolan. It is 100% mongrel.
Who knows from where all those drones come and how aggressive are the drone families.
If one hive has 10% aggressive workers, they surely give to you a lecture.
70 000 bees in the colony and 10% is 7000 bees. It is almost one Langstroth box of bees.
.
when 20 bees sting me during inspection, it is a limit. 6 980 are still waiting their turn.
