well this info. has probably been posted some where before ....

but these ones : (potato leaf early etc.)

Moravsky Div
Glacier,
Kotlas,
Kimberly,
Bloody Butcher,
Imur Prior Beta,
Matina/Tamina

a lot of similarities and nuances of the above group :

There seems to be a group of folks that prefers Moravsky Div.

and a group of happy Campers with Matina /Tamina pref.

I had good consistent success with Kimberly as well ..
