I'll know more this year but from what I've seen so far... Sterling is weak as tubercle and tomsawyer have said, so is Goldings imo. Nugget is pretty good but Cascade, Centennial and Fuggle are strong growers. I'll probably have to dig them up and space them out further because mine are only 6 or so feet apart between varieties. I may drop down to just those that grow well, I want to add Magnum this year.
