I switched to carniolans three years ago. The so-called Yugos were
as bad as the car of that name. Those from Heitkam and Strachan, the Coby
strain, have been good. However, you definitely have to change the way you
work with them; timing of brood production and space needs differ widely
fom Italians.
        I would suggest you be careful where you get them. Some seem to be
crossbred with Caucasians. Some seem to have been bred with a mix of drones
other than Carniolan. Two east coast breeders of Coby bees have not worked
for me. One is still building up his stock. The other does not respond to
inqueries.
        If Italians work for you - remember the adage: IF IT AIN"T BROKE,
DON"T FIX IT.
